A steam power plant operating in a Rakine cycle has saturated vapor at 600 lbf/in^2 leaving the boiler. The turbine exhausts to the condenser operating at 2.23 lbf/in^2. The turbine has an isentropic efficiency of 85% and the pump has an isentropic efficiency of 80%. 1) Find the specific work of the turbine 2) Find the specific work of the pump 3) Fin the specific heat input to the boiler 4) Find the thermal efficiency of the cycle.
