Question

A steady-state system for producing power consist of a pump, heat exchanger and a turbine. Water steam power plant operates on an ideal reheat- regenerative Rankine cycle. Steam enters the highpressure turbine at 10 MPa and \( 550^{\circ} \mathrm{C} \) and leaves at 0.8 MPa . Some steam is extracted at this pressure to heat the feedwater in an open feedwater heater. The rest of the steam is reheated to \( 500^{\circ} \mathrm{C} \) and is expanded in the low-pressure turbine to the condenser pressure of 10 kPa . Determine the entropy generation associated with the reheating and regeneration processes. Assume a source temperature of 1800 K .
