A steady-state heat engine operates on the Rankine cycle.

∎ The steam entering the turbine is 1 kg/s of steam at P = 3.5 MPa and T = 350°C.

∎ The ACTUAL stream exiting the turbine is a mixture of 95% vapor and 5% liquid at P = 50 kPa

∎ The stream entering the pump is saturated liquid at P = 50 kPa

A. Determine the efficiency of the turbine.

B. Estimate the work required by the pump.

C. Estimate the overall efficiency of the heat engine.

D. What is the efficiency of a Carnot heat engine that operates between a high temperature of 350°C and a low temperature that is the same as the temperature of the condenser in this problem?
