If a uniform solid body weighs 50N in air and 30N in water, its specific gravity is close to i. 0.5 ii. 2.0 ii. 1.85 iv. 2.5 v. 5.0 Answer specific gravity =
Specific gravity = 1.67.
The specific gravity of a substance is defined as the ratio of the density of that substance to the density of a reference substance, typically water. Since the weight of a submerged object is reduced by the weight of the fluid it displaces, we can use the difference in weight between the object in air and in water to calculate the volume of water displaced, and hence the density of the object. Dividing the density of the object by the density of water gives the specific gravity. In this case, the specific gravity is (50 N - 30 N) / (50 N - 30 N) = 1.67.

What is the difference between a cost and a benefit?
Answer:
A cost is something you have to give up or sacrifice and a benefit is something that is gained or is helpful.
Explanation:
In a cost-benefit analysis of a system, an engineer is to simply look at the requirements for the system and determine the costs to build the system, both in financial value and energy value. Additionally, the engineer needs to determine the benefits that would come from choosing a particular path of cost. If the benefits outweigh the cost for the project, then the solution is accepted. Else, the cost outweighs the benefit and the solution is rejected.

Sea B = 5.00 m a 60.0°. Sea C que tiene la misma magnitud que A y un ángulo de dirección mayor que el de A en 25.0°. Sea A ⦁ B = 30.0 m2 y B ⦁ C = 35.0 m2 . Encuentre A.
Answer:
\(\| \vec A \| = 6.163\,m\)
Explanation:
Sean A, B y C vectores coplanares tal que:
\(\vec A = (\| \vec A \|\cdot \cos \theta_{A},\| \vec A \|\cdot \sin \theta_{A})\), \(\vec B = (\| \vec B \|\cdot \cos \theta_{B},\| \vec B \|\cdot \sin \theta_{B})\) y \(\vec C = (\| \vec C \|\cdot \cos \theta_{C},\| \vec C \|\cdot \sin \theta_{C})\)
Donde \(\| \vec A \|\), \(\| \vec B \|\) y \(\| \vec C \|\) son las normas o magnitudes respectivas de los vectores A, B y C, mientras que \(\theta_{A}\), \(\theta_{B}\) y \(\theta_{C}\) son las direcciones respectivas de aquellos vectores, medidas en grados sexagesimales.
Por definición de producto escalar, se encuentra que:
\(\vec A \,\bullet\, \vec B = \|\vec A \| \| \vec B \| \cos \theta_{B}\cdot \cos \theta_{A} + \|\vec A \| \| \vec B \| \sin \theta_{B}\cdot \sin \theta_{A}\)
\(\vec B \,\bullet\, \vec C = \|\vec B \| \| \vec C \| \cos \theta_{B}\cdot \cos \theta_{C} + \|\vec B \| \| \vec C \| \sin \theta_{B}\cdot \sin \theta_{C}\)
Asimismo, se sabe que \(\| \vec B \| = 5\,m\), \(\theta_{B} = 60^{\circ}\), \(\vec A \,\bullet \,\vec B = 30\,m^{2}\), \(\vec B\, \bullet\, \vec C = 35\,m^{2}\), \(\|\vec A \| = \| \vec C \|\) y \(\theta_{C} = \theta_{A} + 25^{\circ}\). Entonces, las ecuaciones quedan simplificadas como siguen:
\(30\,m^{2} = 5\|\vec A \| \cdot (\cos 60^{\circ}\cdot \cos \theta_{A} + \sin 60^{\circ}\cdot \sin \theta_{A})\)
\(35\,m^{2} = 5\|\vec A \| \cdot [\cos 60^{\circ}\cdot \cos (\theta_{A}+25^{\circ}) + \sin 60^{\circ}\cdot \sin (\theta_{A}+25^{\circ})]\)
Es decir,
\(30\,m^{2} = \| \vec A \| \cdot (2.5\cdot \cos \theta_{A} + 4.330\cdot \sin \theta_{A})\)
\(35\,m^{2} = \| \vec A \| \cdot [2.5\cdot \cos (\theta_{A}+25^{\circ})+4.330\cdot \sin (\theta_{A}+25^{\circ}})]\)
Luego, se aplica las siguientes identidades trigonométricas para sumas de ángulos:
\(\cos (\theta_{A}+25^{\circ}) = \cos \theta_{A}\cdot \cos 25^{\circ} - \sin \theta_{A}\cdot \sin 25^{\circ}\)
\(\sin (\theta_{A}+25^{\circ}) = \sin \theta_{A}\cdot \cos 25^{\circ} + \cos \theta_{A} \cdot \sin 25^{\circ}\)
Es decir,
\(\cos (\theta_{A}+25^{\circ}) = 0.906\cdot \cos \theta_{A} - 0.423 \cdot \sin \theta_{A}\)
\(\sin (\theta_{A}+25^{\circ}) = 0.906\cdot \sin \theta_{A} + 0.423 \cdot \cos \theta_{A}\)
Las nuevas expresiones son las siguientes:
\(30\,m^{2} = \| \vec A \| \cdot (2.5\cdot \cos \theta_{A} + 4.330\cdot \sin \theta_{A})\)
\(35\,m^{2} = \| \vec A \| \cdot [2.5\cdot (0.906\cdot \cos \theta_{A} - 0.423 \cdot \sin \theta_{A})+4.330\cdot (0.906\cdot \sin \theta_{A} + 0.423 \cdot \cos \theta_{A})]\)
Ahora se simplifican las expresiones, se elimina la norma de \(\vec A\) y se desarrolla y simplifica la ecuación resultante:
\(30\,m^{2} = \| \vec A \| \cdot (2.5\cdot \cos \theta_{A} + 4.330\cdot \sin \theta_{A})\)
\(35\,m^{2} = \| \vec A \| \cdot (4.097\cdot \cos \theta_{A} +2.865\cdot \sin \theta_{A})\)
\(\frac{30\,m^{2}}{2.5\cdot \cos \theta_{A}+ 4.330\cdot \sin \theta_{A}} = \frac{35\,m^{2}}{4.097\cdot \cos \theta_{A} + 2.865\cdot \sin \theta_{A}}\)
\(30\cdot (4.097\cdot \cos \theta_{A} + 2.865\cdot \sin \theta_{A}) = 35\cdot (2.5\cdot \cos \theta_{A}+4.330\cdot \sin \theta_{A})\)
\(122.91\cdot \cos \theta_{A} + 85.95\cdot \sin \theta_{A} = 87.5\cdot \cos \theta_{A} + 151.55\cdot \sin \theta_{A}\)
\(35.41\cdot \cos \theta_{A} = 65.6\cdot \sin \theta_{A}\)
\(\tan \theta_{A} = \frac{35.41}{65.6}\)
\(\tan \theta_{A} = 0.540\)
Ahora se determina el ángulo de \(\vec A\):
\(\theta_{A} = \tan^{-1} \left(0.540\right)\)
La función tangente es positiva en el primer y tercer cuadrantes y tiene un periodicidad de 180 grados, entonces existen al menos dos soluciones del ángulo citado:
\(\theta_{A, 1} \approx 28.369^{\circ}\) y \(\theta_{A, 2} \approx 208.369^{\circ}\)
Ahora, la magnitud de \(\vec A\) es:
\(\| \vec A \| = \frac{35\,m^{2}}{4.097\cdot \cos 28.369^{\circ} + 2.865\cdot \sin 28.369^{\circ}}\)
\(\| \vec A \| = 6.163\,m\)
The steady-state data listed below are claimed for a power cycle operating between hot and cold reservoirs at 1200 K and 400 K, respectively. For each case, evaluate the net power developed by the cycle, in kW, and the thermal efficiency. Also in each case apply the equation below on a time-rate basis to determine whether the cycle operates reversibly, operates irreversibly, or is impossible.
(a) Qh(dot)=600 kW, Qc(dot)=400 kW
(b) Qh(dot)=600 kW, Qc(dot)=0 kW
(c) Qh(dot)=600 kW, Qc(dot)=200 kW
∮ (δQ/T)_b = -σ_cycle
Answer:
(a) Qh(dot)=600 kW, Qc(dot)=400 kW is an irreversible process.
(b) Qh(dot)=600 kW, Qc(dot)=0 kW is an impossible process.
(c) Qh(dot)=600 kW, Qc(dot)=200 kW is a reversible process.
Explanation:
T(hot) = 1200k, T(cold) = 400
efficiency n = (Th - Tc ) / Tc
n = (1200 - 400) / 1200 = 0.667 (this will be the comparison base)
(a)
Qh = 600 kW, Qc = 400 kW
n = (Qh - Qc) / Qh ⇒ (600 - 400) / 600
n = 0.33
0.33 is less than efficiency value from temperature 0.67
∴ it is irreversible process
(b)
Qh = 600 kW, Qc = 0
n = (Qh - Qc) / Qh ⇒ (600 - 0) / 600 = 1
efficiency in any power cycle can never be equal to one.
∴ it is an impossible process.
(c)
Qh = 600 kW, Qc = 200 kW
n = (Qh - Qc) / Qh = (600 - 200) / 600
n = 0.67 (it is equal to efficiency value from temperature)
∴ it is a reversible process

A rigid container is partly filled with a liquid at 1520 kPa. The volume of the liquid is 1.232 litres. At a pressure
of 3039 kPa, the volume of the liquid is 1.231 litres.
a. Calculate the average bulk modulus of elasticity of the liquid
Answer:
Bulk modulus: ß = - ∆p/(∆V/V)
∆p = (3039 - 1520)x10³ = 1519 kPa
∆V = 1231 - 1232 = -1 m³
V = 1232 m³
ß = - 1519/(-1/1232) = 1.87x10^6 kPa = 1.87 GPa
Explanation:
a.The average bulk modulus of elasticity of the liquid is 1.87 GPa
b. Coefficient of compressibility 0.5437 GPa-¹
c Velocity of sound 1.87 x 10^9P
a. Bulk modulus of elasticity
ß = - ∆p/(∆V/V)
First step is to determine ∆p
∆p = (3039 kpa - 1520 kpa)x10³
∆p = 1519 kPa
Second step is to determine ∆V
∆V = 1231 litres - 1232 litres
∆V = -1 m³
Now let determine the Bulk modulus of elasticity
Bulk modulus of elasticity= - 1519/(-1/1232)
Bulk modulus of elasticity= 1.87x10^6 kPa
Bulk modulus of elasticity= 1.87 GPa
b. The coefficient of compressibility
Coefficient of compressibility=β =1/K

Tidal turbines convert the energy of a flowing tide to generate electricity. Early designs of these machines commonly had their rotor attached to a supporting tower mounted on the seabed – see for example Figure QC2.1. A representation of a tide-driven flow of water past a tidal turbine is sketched in Figure QC2.2. An expansion of the flow from d1 to d2 is imagined to occur over the rotor, with half of the expansion (in area) happening upstream of the rotor, and half downstream.
(a) Explain why the active part of the inflow (the streamtube shown in Figure
QC2.2) expands its cross-section as it passes the turbine. (2)
Analysis for the analogous situation of a wind turbine with uniform inflow, attributed to Albert Betz and others in the 1920s, demonstrated that for optimum efficiency of energy extraction from the inflow, the far upstream flow speed should be reduced by the turbine such that the far downstream speed is 1/3rd of the far upstream speed.
(b) Suggest three reasons why this theoretical maximum efficiency will in general
not be achieved in a practical tidal turbine deployment. (3)
(c) The Alstom 1.4 MW OceadeTM turbine has a rotor diameter of 18 m. The
supporting tower has a height of 15 m and a diameter of 3 m. In a 3 ms-1 tidal
flow, estimate the total fluid loading experienced by the whole machine. State
and justify the assumptions that you make in arriving at this estimate. (12)
(d) How would you expect to use these estimates of forces when designing the
turbine and tower structure?
(a) The active part of the inflow expands its cross-section as it passes the tidal turbine due to conservation of mass and energy.
(b) Several reasons contribute to the theoretical maximum efficiency not being achieved in practical tidal turbine deployments, including turbulence, non-uniform flow, and mechanical losses.
(c) Estimating the total fluid loading on the Alstom 1.4 MW OceadeTM turbine requires considering the flow velocity, rotor and tower dimensions, and making assumptions about the flow characteristics and structural properties.
(d) The estimates of forces obtained from the fluid loading calculations are essential for designing the turbine and tower structure by ensuring that they can withstand the anticipated loads and stresses.
(a) The active part of the inflow expands its cross-section as it passes the tidal turbine due to the principle of conservation of mass and energy. As the tidal flow encounters the turbine rotor, some of the kinetic energy of the flow is converted into mechanical energy to drive the turbine. To satisfy the conservation of mass, the cross-sectional area of the flow must increase to compensate for the reduction in flow velocity caused by energy extraction.
(b) Achieving the theoretical maximum efficiency in practical tidal turbine deployments is challenging due to several reasons. First, tidal flows are often characterized by turbulence, which disrupts the uniformity of the flow and reduces overall efficiency. Second, tidal flow itself is not uniformly distributed, and the flow characteristics vary with tidal cycles, further impacting efficiency. Lastly, mechanical losses in the turbine's components, such as friction and resistance, reduce the efficiency of energy conversion.
(c) Estimating the total fluid loading on the Alstom 1.4 MW OceadeTM turbine involves considering the flow velocity, rotor diameter, and tower dimensions. Assuming a tidal flow velocity of 3 m/s, the fluid loading can be estimated by considering the momentum change and forces acting on the rotor and tower surfaces. Assumptions may include a simplified flow model, neglecting factors such as turbulence and non-uniform flow, and assuming a stationary tower. These assumptions simplify the calculation while providing a reasonable estimate of the fluid loading.
(d) The estimates of forces obtained from the fluid loading calculations are crucial for designing the turbine and tower structure. These estimates help engineers determine the required structural strength, material selection, and design considerations to ensure that the turbine and tower can withstand the anticipated fluid forces and mechanical stresses. By considering the estimated forces, designers can optimize the structural integrity, stability, and reliability of the turbine and tower, ensuring safe and efficient operation in tidal environments.

An asphalt concrete specimen has the following properties: Asphalt content = 5.5% by total weight of mix Bulk specific gravity of the mix = 2.475 Theoretical maximum specific gravity = 2.563 Bulk specific gravity of aggregate = 2.689 Ignoring absorption, calculate the percents VTM, VMA, and VFA.
This high value indicates that the specimen has a very low void content due to high asphalt content. To calculate the percents VTM, VMA, and VFA, we first need to determine the bulk specific gravity of the asphalt in the mix. We can do this using the following formula:
Bulk specific gravity of asphalt (Gmb) = (Gmm x Pba) / (Pbm x 100)
Where Gmm is the theoretical maximum specific gravity, Pba is the percent asphalt content by total weight of mix, and Pbm is the bulk specific gravity of the mix. Plugging in the given values, we get:
Gmb = (2.563 x 5.5) / (2.475 x 100) = 0.057
Now we can calculate the percent VTM using the following formula:
VTM = ((Gmb / Gsb) - 1) x 100
Where Gsb is the bulk specific gravity of the aggregate. Plugging in the given values, we get:
VTM = ((0.057 / 2.689) - 1) x 100 = -95.9%
This negative value indicates that the specimen has a high air void content.

The ionic radius of Ca²⁺ is 100 pm, K⁺ is 138 pm, Cl⁻ is 181 pm, and S²⁻ is 184 pm, therefore option d is the right choice.
The influence of an ion's nucleus on its electron cloud extends outward to a distance called the ionic radius.
When an atom loses or gains an electron, an ion is created. A cation is formed when an atom loses an electron, and an anion is formed when an atom gains an electron. The ionic radius is the furthest point away from the ion's nucleus that its outermost shell can extend.
A cation's atomic size will be lower than that of its parent atom. Compared to its parent atom, an anion is comparatively large. That's because the net effective nuclear charge gets drowned out by the repulsion between electrons caused by an atom gaining electrons.

A site is underlain by a soil that has a unit weight of 118 lb/ft3. From laboratory shear strength tests that closely simulated the field conditions, the total stress parameters were measured to be C total = 250 lb/ft2 and φ total = 29°. Estimate the shear strength on a horizontal plane at a depth of 12 ft below the ground surface at this site in lbs/ sq ft
Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²
Explanation:
Given that;
Weight of soil r = 118 lb/ft³
stress parameter C = 250 lb/ft²
φ total = 29°
depth Z = 12 ft
The shear strength on a horizontal plane at a depth of 12ft
ζ = C + δtanφ
where δ = normal stress
normal stress δ = r × z = 118 × 12 = 1416
so
ζ = C + δtanφ
ζ = 250 + 1416(tan29°)
ζ = 250 + 1416(tan29°)
ζ = 250 + 784.9016
ζ = 1034.9015 lb/ft²
Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

if the tensile strength of the steel is 100,000 psi (lb/in2) , we want a safety factor of 2, and the density of steel in 0.283 lb/in3, what will the minimum weight of the cable be?
The minimum weight of the cable will be X pounds.
To calculate the minimum weight of the cable, we need to consider the safety factor and the density of steel. The safety factor indicates the level of redundancy built into the design to ensure structural integrity. In this case, the safety factor is 2, meaning the cable needs to withstand twice the anticipated load.
The formula to calculate the minimum weight of the cable is:
Minimum weight = (Safety factor * Tensile strength * Cross-sectional area) / Density
Given the tensile strength of the steel (100,000 psi), the safety factor of 2, and the density of steel (0.283 lb/in^3), we can plug in these values into the formula to find the minimum weight of the cable. The cross-sectional area of the cable needs to be known to obtain the final weight.
