Our space program requires a portable engine to generate electricity for a space station. It is proposed to use sodium (Tc 2300 K; Pc 195 bar; 0; CP/R 2. 5) as the working fluid in a customized form of a "Rankine" cycle. The high-temperature stream is not superheated before running through the turbine. Instead, the saturated vapor (T 1444 K, P sat 0. 828 MPa) is run directly through the (100% efficient, adiabatic) turbine. The rest of the Rankine cycle is the usual. That is, the outlet stream from the turbine passes through a condenser where it is cooled to saturated liquid at 1155 K (this is the normal boiling temperature of sodium), which is pumped (neglect the pump work) back into the boiler. (a) Estimate the quality coming out of the turbine. (b) Compute the work output per unit of heat input to the cycle,

Total unit weight, γ = 1.0825 kg/m³Void ratio, e = 3Porosity, n = 0.75

Water content (w%) = 12%Degree of saturation (Sr) = 75%Specific gravity of solids (Gs) = 2.65We have to calculate the total unit weight, void ratio (e), and porosity (n).Calculation:

First, we have to calculate the dry unit weight, γd

Dry unit weight, γd = γw / (1 + w%)

Let's calculate γw

Water content (w%) = 12%

So, moisture content (w) = w% * γd / 100= 12/100 * 1.65= 0.198 kg/kg of dry soil

Total weight of soil (Wt) = Weight of solids (Ws) + Weight of water (Ww)

Weight of solids (Ws) = Volume of solids (Vs) * Gs * γw/Vs = 1

Total volume of soil = Volume of solids (Vs) + Volume of voids (Vv)

Let's calculate Vv Degree of saturation (Sr) = 75%Vv/Vs = Sr / (1 - Sr)= 0.75 / 0.25= 3

Total volume of soil = Volume of solids (Vs) + Volume of voids (Vv)= 1 + 3= 4m^3

Let's calculate the weight of water,

WwWw = Wt - WsWw = 4 * 0.12 = 0.48 kg

Weight of solids, Ws = Gs * γs * Vsγs = (Wt - Ww) / Vst = (1 - 0.12) * 1.65= 1.452 kg/ m^3

Ws = Gs * γs * Vs= 2.65 * 1.452= 3.85 kg

Total unit weight, γ= Wt / Vt= (Ws + Ww) / Vt= (3.85 + 0.48) / 4= 1.0825 kg/m^3

Now, calculate the void ratio, eVv/Vs = 3Vv / Vt = Vv / (Vs + Vv) = 3 / 4e = Vv / Vs = 3 / 1 = 3

Porosity, n= Vv / Vt= 3 / 4= 0.75

True, it is generally true that it takes less gas to restart a vehicle than it does to let it idle for one minute.

The amount of gas used while idling varies depending on several factors, including the size of the engine, the age of the vehicle, and the outside temperature. However, most experts agree that idling for more than 10 seconds uses more fuel than restarting the engine.

Restarting a vehicle uses a small amount of gas, typically about 10 seconds' worth. This is because modern vehicles are designed with fuel injection systems that use electronic sensors to adjust the fuel-to-air ratio, which means that very little fuel is used during the initial startup.

There are also environmental benefits to turning off the engine instead of idling. Idling for extended periods can contribute to air pollution and greenhouse gas emissions, as well as wear and tear on the engine.

Explanation:

I have asked question in my profile please tell me the answer

Answer:

the magnitude of F_A is 752 N

the direction theta of F_A is 57.9°

Explanations:

Given that,

Resultant force = 1330 N in x direction

∑Fx = R

from the diagram of the question which i uploaded along with this answer

FB = 800 N

FAsin∅ + FBcos30 = 1330 N

FAsin∅ = 1330 - (800 × cos30)

FA = 637.18 / sin∅

Now ∑Fx = 0

FAcos∅ - FBsin30 = 0

we substitute for FA

(637.18 / sin∅)cos∅ = 800 × sin30

637.18 / 800 × sin30 = sin∅/cos∅

and we know that { sin∅/cos∅ = tan∅)

so tan∅ = 1.59295

∅ = 57.88° ≈ 57.9°

THEREFORE FROM THE EQUATION

FA = 637.18 / sin∅

we substitute ∅

so FA = 637.18 / sin57.88

FA = 752 N

[b]. the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.

Explanation:

Atoms are referred to be the smallest units of a substance although it can be sub-divided into smaller units such as proton, neutron and electron. When atoms combines in group they form a molecule.

From the question above it is seen that two substances were mixed together to give two ending substances that is:

substance A [ colorless liquid with a strong smell] + substance B[white solid with no smell] ---------> substance C[ repeating group of atoms shown above on the right] + substance D.

The ending substance that is, substance C is the same substance as substance A which is the colorless liquid with a strong smell.

When the substance A reacted with substance B, it gives substance C and D that is the ending substances are the products of the reaction between A and B.

Hence, the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.

The total elongation (ΔL) = 15,000 psi x 0.0005 = 0.075 inches

The total elongation of a steel bar, originally 25 inches long, when the induced tensile stress is 15,000 psi can be calculated as follows:

Using Hooke's Law, the elongation is equal to the stress multiplied by the strain:

Elongation (ΔL) = Stress (σ) x Strain (ε)

Elongation (ΔL) = 15,000 psi x Strain

The modulus of elasticity for steel is 30,000,000 psi, so the strain is equal to the stress divided by the modulus of elasticity:

Strain (ε) = Stress (σ) / Modulus of Elasticity (E)

Strain (ε) = 15,000 psi / 30,000,000 psi

Strain (ε) = 0.0005

Therefore, the total elongation (ΔL) = 15,000 psi x 0.0005 = 0.075 inches

A photo multiplier tube (PMT) amplifies the intensity of light by converting photons into electrical signals.

A photo multiplier tube (PMT) is a highly sensitive device used to detect and measure low levels of light. It consists of a vacuum tube with several important components. The PMT starts with a photocathode, which is a thin metal film that emits electrons when struck by photons. When light enters the PMT, it interacts with the photocathode, causing the emission of electrons through the photoelectric effect.

The emitted electrons are then accelerated by a high voltage applied across the PMT, creating an electron cascade. This acceleration occurs in a series of dynodes, which are metal plates that have a slightly higher voltage than the previous dynode. As the electrons strike each dynode, they release more electrons, resulting in a significant amplification of the signal.

At the end of the electron cascade, the amplified signal reaches an anode, where it is collected as an electrical pulse. This pulse can then be processed and measured by external electronic devices for further analysis or recording. The overall amplification of the PMT can range from thousands to millions, depending on the number of dynodes and their voltages.

The given code includes function declarations of func1() and func2() and the question asks for the correct statement about their declarations. The correct statement is that the extern keyword applied to func1() makes it global, while func2() will only be visible within the current source file scope.

To explain further, the extern keyword extends the visibility of a function or variable to the entire program, allowing it to be accessed from other files. By using extern with func1() and not with func2(), func1() becomes global, which means it can be accessed by other files as well. On the other hand, func2() will only be visible within the current file and cannot be accessed from other files.

Therefore, option A is the correct answer as it explains that func1() is global due to the extern keyword, while func2() is only visible to the current source file scope.
