Extracted text: A steam power plant operating in a Rankine cycle has saturated vapor at 4.0 MPa leaving the boiler. The turbine exhausts to the condenser, operating at 75 kPa, and the mass flow rate of the working fluid is 5.0 kg/hr. The turbine efficiency is 0.85. Solve for the work produced by the turbine and the pump (in Watts), the heat transfer in the boiler (in Watts), and the Rankine cycle efficiency. efficiency.
