Consider a steam power plant operating the ideal reheat Rankine cycle. Steam enters the high-pressure turbine at 14 MPa and 600C and is condensed in the condenser at a pressure of 10 kPa. The quality of the steam (x) at the exit of the low-pressure turbine is 0.896. Assume the steam is reheated to the inlet temperature (600C) of the high-pressure turbine. (a) Determine the pressure (P2 = P3) at which the steam should be reheated and corresponding specific enthalpy values (h) of the State 2 and 3 (10 pts). (b) Determine the thermal efficiency of the cycle (10 pts). (c) Sketch the processes on the T-s diagram labeled with temperature values at each state (5 pts).
