Consider an ideal steam regenerative Rankine cycle with two feedwater heaters, one closed and one open. Steam enters the turbine at 12.5 MPa and 550°C and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 0.8 MPa for the closed feedwater heater and at 0.3 MPa for the open one. The feedwater is heated to the condensation temperature of the extracted steam in the closed feedwater heater. The extracted steam leaves the closed feedwater heater as a saturated liquid, which is subsequently throttled to the open feedwater heater. Show the cycle on a T-s diagram with respect to saturation lines, and determine (a) the mass flow rate of steam through the boiler for a net power output of 250 MW and (b) the thermal efficiency of the cycle. 8 Turbine Boiler Closed 1-y - z FWH (10 Орen PII FWH Condenser

PLEASE ANSWER QUICKLY
The stress and a pipe varies jointly with the internal pressure and the diameter of the pipe, and inversely with the square of the thickness of the pipe. The stress is 200 pounds per square inch when the diameter is 4 inches, the thickness is 0.40 inches, and the internal pressure is 25 pounds per square inch. Find distressed wood and internal pressure is 50 pounds per square inch if the diameter is 10 inches and a thickness is 0.50 inches. Define variables Stress in pipe Internal pressure of pipe Diameter of pipe Thickness of pipe Find k Update formula Answer question
What is the difference between internal force and external force? And give an example of each.
There is a steel that has been rolled and you want to verify its mechanical properties, so two samples are cut, one in the direction of the rolling and the other perpendicular to it. In which case both samples have the same properties and in which case they are not the same.
The new line of go-karts will have a two-stroke internal combustion engine. The engine generates 35 horsepower at a mean speed of 2000 rpm. The biggest variation in energy per revolution, according to dynamic analysis, is 25% of the mean energy. Design a flywheel to go along with this engine such that the maximum coefficient of speed fluctuation is 0.01. Your design should include all necessary details, such as the design calculations, the appropriate material, detailed dimensions, and manufacturing procedures. Note: As a design problem, there is more than one acceptable solution. One design, though, might be superior to others.
1. Why does a surface composed of a particular material get dirtied? 2. Why do engineering metals and alloys break, despite the fact that they can't be prevented from doing so? Please explain in full detail! Thank you
Selasi wants a shaft of 5/8 inches diameter to be used in his design project of which he is considering a design factor of 3. He hopes to get the same shaft size or 11/16 inch diameter shaft in the market for his design. So he decided to send his apprentice, Amuzu to the market. Unfortunately, when Amuzu went to the market, there were 1⁄2 inch, 9/16 inch, 3⁄4 inch, and 7/8 inch sizes available in the first shop. Amuzu decided to buy the nearest shaft size in the first shop instead of checking in the other shops where he could have gotten either 5/8 inch or 11/16 inch sizes.a. Discuss the consequences Selasi would incur in his design project if Amuzu had bought 9/16 inch size shaft. b. Discuss the consequences Selasi would incur in his design project if Amuzu had bought 3⁄4 inch size shaft.
Asap Thanks sir
can you please find solution for this question
You have been asked to obtain an object/structure/component that has failed (It may come fromyour home, workshop, an automobile repair shop, a machine shop, and so on) and investigate to:1. Determine the cause and type of failure (i.e., simple fracture, fatigue, creep).2. What are the working and environmental conditions that causes the failure?3. Propose measures that can be taken to prevent future incidents of this type of failure.4. After you have determined the failure type of your case study, your leader asked you to writeshortly about the other mechanisms of failures.
In your own words, state and justify your assumptions and comment on your working.Marks will be assigned for the quality of the presentation of the working and od the comments.
