A steam power plant operates on the ideal Rankine cycle. The steam enters the turbine at 7.0 MPa and 550°C. It discharges to the condenser at 20 kPa. Let the steam flow rate be 5 kg/s. The steam receives heat from the combustion gases in the furnace of the steam generator; assume the combustion gases change temperature from 2000 K to 425 K in flowing through the steam generator. The cooling water enters the condenser at 20°C and leaves at 40°C. T0 is also 20°C. Determine (a) the cycle thermal efficiency, and (b) the cycle irreversibility

Question
A steam power plant operates on the ideal Rankine cycle. The steam enters the
turbine at 7.0 MPa and 550°C.
It discharges to the condenser at 20 kPa. Let the steam flow rate be 5 kg/s. The steam receives heat
from the combustion gases in the furnace of the steam generator; assume the combustion gases
change temperature from 2000 K to 425 K in flowing through the steam generator. The cooling
water enters the condenser at 20°C and leaves at 40°C. T0 is also 20°C. Determine (a) the cycle
thermal efficiency, and (b) the cycle irreversibility
