Superheated steam from the boiler is delivered to a turbine at 650 C and 8.5 MPa. The turbine exhausts at 0.01 MPa. Given that the turbine is 75% efficient, we need to determine the following: a. The actual work of the turbine.

b. The actual outlet temperature and quality (if applicable) of the exhaust from the turbine.c. If the steam exhaust is condensed (in a condenser) to a saturated liquid, what is the work required by the pump to bring the liquid to the boiler pressure (8.5 MPa).Solution:a) The turbine's actual work output (Wactual) = η (energy input)or Wactual = η (energy input) = η (h1 - h2)Here, η = 75% = 0.75. h1 = enthalpy of the steam entering the turbine = 3344.7 kJ/kg. h2 = enthalpy of the steam leaving the turbine = ?Using the steam tables, h2 = 2275 kJ/kg.Therefore,Wactual = 0.75 (3344.7 - 2275)kJ/kg = 706.7 kJ/kg.b) At turbine outlet, steam pressure P2 = 0.01 MPa.

The steam table shows that at this pressure the saturation temperature T2 is 45.8°C.Hence, the steam leaving the turbine is superheated since T2 > 45.8°C. Let us assume that the steam is superheated by ΔT. Therefore, the steam temperature leaving the turbine is:T2 + ΔT = 650°CT2 = 650 - ΔT°CAt 650°C, the superheated steam table gives us the enthalpy of superheated steam as 3454 kJ/kg.Therefore, the enthalpy of superheated steam at 650 - ΔT°C is: (3454 - Cp ΔT), where Cp is the specific heat capacity of superheated steam at constant pressure.Cp of superheated steam is not given, but its average value can be assumed as 2.1 kJ/kg K over the temperature range of 400 - 800°C.Therefore, h2 = 2275 kJ/kg + (3454 - 2.1 ΔT) kJ/kg2275 kJ/kg + 3454 kJ/kg - 2.1 ΔT kJ/kg = 5729 kJ/kg - 2.1 ΔT kJ/kgFor superheated steam, h2 = Cp T2.

Inspectors

Explanation:

Inspectors are workers that are involved in the construction industry. Most of them can be called a building inspector due to their job consists mostly of inspecting electrical, mechanical or plumbing systems. Half of the people who are inspecting work for the local government. They mostly ensure that everything is up to date and follows the local government standards. The inspector's work begins even before the construction starts. They analyze the structural integrity of the blueprints, ensure that everything is safe, and inspect the location of the actual building. During the construction process they inspect the foundation, plumbing, electrical wiring, framing, and the mechanical system. They may issue a occupancy permit once the building is finished. Inspectors are required to have a thorough knowledge of their job and how it works. They are also required to know all the local building codes and regulations in order to determine whether or not the building is safe for use. Generally a good background and having expertise in electrical or plumbing systems is very desirable. Working conditions are similar to most construction workers although it may be less physically demanding. Inspectors normally take ladders, navigate through messy areas filled with tools or work in confined spaces.

Given that,

Mass of the object 1, m = 107.01 grams

To find,

Force on the object.

Solution,

The force acting on the object is gravitational force. The force is given by the formula as follow :

F = mg

g is acceleration due to gravity

F = 0.10701 kg × 9.8 m/s²

F = 1.048 N

So, the force acting on object 1 is 1.048 N.

Rigid schedule 80 pvc shall have a minimum burial depth of 18 inches.

Rigid schedule 80 PVC is a type of polyvinyl chloride pipe commonly used in various applications, including underground installations. The minimum burial depth refers to the depth at which the pipe should be buried to ensure proper protection and structural integrity.

The required minimum burial depth for rigid schedule 80 PVC is determined by factors such as the type of soil, traffic loads, and environmental conditions. It is essential to follow local building codes and regulations, as they may specify specific requirements for burial depths. Generally, the recommended minimum burial depth for rigid schedule 80 PVC ranges from 18 to 24 inches.

Proper burial depth helps protect the PVC pipe from external stresses, such as vehicle traffic or ground movement. It also safeguards the pipe from potential damage caused by temperature fluctuations or exposure to sunlight. By burying the pipe at the appropriate depth, the risk of accidental damage and potential leaks or breaks is significantly reduced.

The continuity equation allows finding the results for the speed and flow of the outlet pipe are:

Fluid mechanics studies the movement and fluid dynamics, it is described  by two fundamental relationships:

          \(P_1 + \frac{1}{2} \rho v_1^2 + \rho g y_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g y_2\)  

Where P is the pressure, v the velocity, y the height, the subscripts are two selected points of interest in the pipe.

            \(A_1v_1 = A_2 v_2\)

Where A₁ and A₂ is the area of ​​the inlet and outlet pipes and v₁ and v₂ are the velocities of the fluid at the inlet and outlet

They indicate the inlet and outlet diameters of the pipe are d₁ = 0.02 m and d₂ = 0.1 m, the inlet velocity v₁ = 10 m / s, with the continuity equation let's find the outlet velocity

         \(v_2 = ( \frac{A_1}{A_2} )^2 \ v_1\)  

the cross section of the tavern is

        A = \(\pi r^2 = \pi \ d^2/4\)  

Where r is the radius and d is the diameter

Let's substitutes

        \(v_2 = (\frac{d_1}{d_2} )^2 \ v_1\)  

        \(v_2 = (\frac{0.02}{0.1} )^2 \ 10\)  

        v₂ = 0.4 m / s

The flow  (Q) is defined as the amount of liquid that passes through the section of the pipe per unit of time, we can see that this is the same conservation of mass, therefore

        Q = A v

        Q = \(\pi \frac{d_2^2}{4} \ v_2\)π d2 ^ 2 v2

        Q = \(\pi \ \frac{0.1^2}{4} \ 0.4\)

        Q = 3.14 10⁻³ m ^ 3 / s

As the transported liquid is water

         1 liter water = 1 kg

Consequently

         1 m³ = 1000 liter = 1000 kg of water

Let's reduce the flow

         Q = 3.14 10⁻³ m³/s ( \(\frac{10^3 kg}{1 m^3}\) )

         Q = 3.14 kg / s

In conclusion using the continuity equation we can find the results for the speed and flow of the outlet pipe are:

A spud wrench is distinct from a pipe wrench because it should be used with an extension handle.

An adjustable wrench that is used to work on pipes is called a pipe wrench. Threaded galvanized steel, black iron, or other similar metal pipes are typically the most common application for pipe wrenches. When tightened, the two serrated jaws of a pipe wrench dig into the pipe for grip.

The f-clamp was made with a big opening capacity in mind. The f-clamp has a slider bar that lets you easily change the opening capacity for a lot of different applications. When a C-Clamp's opening capacity is too small, this has made the f-clamp a popular alternative.

A spud wrench differs from a pipe wrench mainly in the design of their jaws and their adjustability. A spud wrench has smooth jaws and is not adjustable, whereas a pipe wrench typically has serrated jaws and is adjustable. Use of handle extension is not recommended for either tool.

In what way a spud wrench is different from a pipe wrench relies heavily on their function and design. Notably, the difference can be found primarily in their jaws and adjustability.

A spud wrench, intended for use in the ironwork and bridgework professions, has smooth jaws that prevent any marring of surfaces. This implies that answer option B is correct. In contrast, a pipe wrench typically has serrated jaws to grip pipes and other rounded surfaces better.

Another significant difference lies in their adjustability. A spud wrench is not adjustable whilst a pipe wrench typically has adjustable jaws, indicating that answer option A is also true.

In terms of length, a spud wrench can be longer or shorter, depending on the specific use case, so option C is not generally true. Using a handle extension is typically not recommended for spud wrenches or pipe wrenches as it may exceed the tool's designed capacity, rendering option D false.
