Problem 5-Irreversible Power cycle A simple power plant cycle has saturated liquid water from a condenser at 100 kPa pumped into a boiler operating at 1.0 MPa. The steam leaves the boiler at 350 °C and is expanded through a turbine with the exit stream having a quality between 0 and 1. If the turbine is 80% efficient and the pump is 90% efficient in this Rankine cycle, what is the overall efficiency of the power cycle?
