A steam power plant operates on an ideal regenerative Rankine cycle with two open feedwater heaters. Steam enters the turbine at 10 MPa and 600C and exhausts to the condenser at 5 kPa.Steam is extracted from the turbine at 0.6 and 0.2 MPa. Water leaves both feedwater heaters as a saturated liquid. The mass flow rate of the steam through the boiler is 22 kg/s. Show the cycle on a T-s diagram, and
determine (a) the net power output of the power plant and (b) the thermal efficiency of the cycle.
