3. (10 pts) A simple Rankine cycle operates between the pressures of 10 kPa and 6 MPa. Steam exits the boiler at 550°C, liquid exits the condenser at 40°C,the "wet steam" exiting the turbine has a quality of90%, the pump efficiency is 64% and the net power output from the system is 87.2 MW. Determine: (2 pts) The mass flow rate through the system, inkg/s. (2 pts) The rate of heat rejection from the condenser,in kW. (2 pts) The rate of heat input, in kW. (2 pts) The thermal efficiency. (2 pts) The isentropic efficiency of the turbine.
