In an ideal open feedwater heater Rankine cycle, water leaves the condenser at 100 kPa and from the boiler at 500 *C and 3 MPa pressure. The water emerges as a saturated liquid at 400 kPa pressure from the open feed water shown in the figure. According to this; a) Show the cycle in a T-s diagram with saturated liquid and saturated vapor curves. b) Find the total pump work (kJ/kg). c) Find the ratio (y) of the mass of steam leaving to heat the turbine feedwater to the mass of steam entering the high pressure turbine. d) Find the turbine work (kJ/kg). e) Find the amount of inlet 1 (kJ/kg). f) Find the efficiency of the cycle.
