Rate energy given off by heat transfer to to cold thermal

A steam power plant has, at the turbine entrance, saturated vapor with a pressure of 40 bar. The turbine exit is at 50 degrees C. The pump entrance is at 50 degrees C as well, and its exit is saturated liquid at 40 bar. The pump has an isentropic pump efficiency of 0.8. a) What is its thermal efficiency? b) At what rate is energy being given off by heat transfer to the cold thermal reservoir?
