Read the questions carefully and answer with complete solution and units. Use the steam tables provided and use 4 decimal places for solving. Final answers shown are in 2 decimal places. Draw the T-S diagrams properly with respect to the saturation line A steam power plant uses the ideal Reheat-Regenerative Rankine cycle where the steam enters the high-pressure turbine at 4 MPa and 300C. It partially expands to 600 kPa where some steam is extracted for feedwater heating while the rest is reheated to the same temperature. After expanding again, it enters the condenser at 10 kPa. Sketch the schematic diagram and the TS diagram with labeled points, and solve for mass taken for feedwater heating, Qa, Qr, Wt, Wp, Wnet, thermal efficiency, and Steam rate.

The unpro- cessed honey is stored in large vats, then pumped though pipes into heating units before being pumped through another pipe to be bottled. The pipe carrying the honey from a storage container, which is 11 m tall, to a heating unit is 5 m long and has a diameter of 10 cm. Prior to being heated the honey is kept at 25°C.
