Steam is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 10 MPa and saturated liquid exits the condenser at a pressure of 0.01 MPa. The net power output (W⋅ net) of the cycle is 150 MW. The turbine and the pump both have an isentropic efficiency of 85%. If the boiler receives heat from a source at 1200oC and the condenser rejects heat to a reservoir at 25oC,
(a) Identify the device of maximum energy destruction (boiler: 0; turbine: 1; condenser: 3; pump: 4),
(b) Determine the energetic efficiency of the cycle and
(c) Draw an energy flow diagram for the cycle. Assume the atmospheric conditions to be 100 kPa and 25oC.
