A simple but non-ideal Rankine cycle operates with water as the working fluid and operating between pressure limits of 75 kPa and 10 MPa. Water enters the pump subcooled by 4°C and 3200 kJ/kg of heat is added in the boiler. The pump has an efficiency of 92% while the isentropic efficiency of the turbine is 94%. Assume there are no pressure losses in the condenser and boiler, and that both the pump and turbine are adiabatic. 1. What is the enthalpy, in kJ/kg, of the turbine outlet? Report your answer to one decimal place using rounding. 2. How much heat is rejected by the cycle, in kJ/kg? Round your answer to the nearest whole number. 3. What is the net work produced by the cycle in kJ/kg? Round your answer to the nearest whole number. 4. What is the thermal efficiency of the cycle. Report your answer as a percentage (number between 0 and 100) and to one decimal place using rounding.

Question
A simple but non-ideal Rankine cycle operates with water as the working fluid and operating between pressure limits of 75 kPa and 10 MPa. Water enters the pump subcooled by 4°C and 3200 kJ/kg of heat is added in the boiler. The pump has an efficiency of 92% while the isentropic efficiency of the turbine is 94%. Assume there are no pressure losses in the condenser and boiler, and that both the pump and turbine are adiabatic.
1. What is the enthalpy, in kJ/kg, of the turbine outlet? Report your answer to one decimal place using rounding.
2. How much heat is rejected by the cycle, in kJ/kg? Round your answer to the nearest whole number.
3. What is the net work produced by the cycle in kJ/kg? Round your answer to the nearest whole number.
4. What is the thermal efficiency of the cycle. Report your answer as a percentage (number between 0 and 100) and to one decimal place using rounding.
