2. Consider a steam power plant that operates on an ideal reheat-regenerative Rankine cycle with one open and one closed feedwater heater. 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. extracted from the low pressure turbine at a pressure of 0.5 MPa. Condensate leaves the closed feedwater heater as saturated liquid at the respective extraction pressure. The feedwater stream leaves the closed feedwater heater at a temperature equal to the saturation temperature at the respective the extraction pressure Steam for the open feedwater heater is (Ans: (c) 192.305 kJ/kg, 656.06 kJ/kg. I 101.062 klikg, 1087.29 klik (e) 1089.67 kJ/kg. (f) 1446.75 kJ/kg, (g-15.84 kJ/k ·(h) 0.4895) (d) 0.1 7261, 0.13132. a. Fill the column of the mass flow and pressure in the table (next page. b. Show the cycle on a T - s diagram. c. Find hz, h4, ho, hi d. Calculate y and y e. Fine hz f. Calculate the specifie work of the turbine ((kJ/kg)) 8. Calculate the total specific work of the pumps (Wp(kJ/kg)) h. Calculate the efficiency of this cyele. Wpump
