Consider a steam power plant that operates on an ideal reheat- regenerative Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater. Steam enters the turbine at 15 MPa and 600°C and is condensed in the condenser at a pressure of 10 kPa. Some steam is extracted from the turbine at 4 MPa for the closed feedwater heater, and the remaining steam is reheated at the same pressure to 600°C. The extracted steam is completely condensed in the heater and is pumped to 15 MPa before it mixes with the feedwater at the same pressure. Steam for the open feed- water heater is extracted from the low-pressure turbine at a pressure of 0.5 MPa. Draw the cycle on T-S diagram and determine the fractions of steam extracted from the turbine. High-P Low-P 15 MP 600°C Boiler 4 MPa Reheater P-Pu- 4 MP 600 °C 1-y-z 10 AP
