2. A steam power plant uses the ideal Regenarative Rankine cycle with single open feedwater heater where the steam enters the high pressure turbine at 4 μPa and 300c. Alt partially expands to 600 kPa then some steam is extracted at this point. The remaining steam expands and enters the condenser at 10 kPa. Sketch the schematic diagram and the TS diagram with labeled points, and solve for marr taken for feedwater heating, Qa, Qr, Wt, Wp. Whet, thermal efficienc and steam rate. Neglect the condensate pump work!
