A.S.A.P

An ideal reheat regenerative Rankine cycle with one open feedwater heater. The boiler and condenser operate at 10 MPa and 15 kPa. The reheater operates at 2 MPa and the feedwater heater operates at 0.6 MPa. Both turbines operate with an inlet temperature of 500°C. Given that the isentropic efficiencies of turbine and pump are 80% and 95%, respectively. Part 1 1. Show the cycle on a T-S diagram with respect to saturation lines. 2. Determine the thermal efficiency for this cycle. 3. Now assume that both compression and expansion processes in the pump and turbine are isentropic. Calculate the thermal efficiency of the ideal cycle.
