Problem 2 (Rankine Cycle) The boiler of a Rankine power cycle operates at 7000 kPa and the condenser at 50 kPa. At the turbine inlet, the temperature is 550°C. The pump is effectively isentropic, the isentropic efficiency of the turbine is 85 percent, pressure losses in the boiler and condenser are negligible, and the water leaving the condenser is subcooled by 6.3°C. The boiler is sized for a mass flow rate of 20 kg/s. You are asked to: Represent the cycle on a T-s diagram. Compute the rate at which heat is added in the boiler. Compute the power required to operate the pump. Determine the net power produced by the cycle. Compute the thermal efficiency.

Problem 2 (Rankine Cycle)
The boiler of a Rankine power cycle operates at 7000 kPa and the condenser at 50 kPa. At the turbine
inlet, the temperature is 550°C. The pump is effectively isentropic, the isentropic efficiency of the
turbine is 85 percent, pressure losses in the boiler and condenser are negligible, and the water leaving
the condenser is subcooled by 6.3°C. The boiler is sized for a mass flow rate of 20 kg/s. You are asked to:
Represent the cycle on a T-s diagram.
Compute the rate at which heat is added in the boiler.
Compute the power required to operate the pump.
Determine the net power produced by the cycle.
Compute the thermal efficiency.
