In a Rankine cycle, water leaves the condenser as saturated liquid with a pressure of 20 kPa. Steam leaves the boiler at 4.5 MPa and 400 C. Assume a pump isentropic efficiency of 0.8 and a turbine isentropic efficiency of 0.9. Also assume that there are no pressure losses in the boiler and condenser. (a) Show the cycle on a T-s diagram. (b) Draw the schematic of the system. (c) Determine the net power output.
