For the vapor power cycle, steam enters the at 3 MPa and 500 C and leaves at 70 kPa and 200 C. The system is operating at steady state with no changes in kinetic or potential energy and we assume no stray heat transfer. The mass flow rate is 10 kg/s. Find the following. Inlet enthalpy ___________ Exit enthalpy ___________ Inlet entropy ___________ Exit entropy ___________ A) What is the general equation to determine the rate of entropy production? B) What is rate of entropy production per kg steam for this turbine? C) Calculate the isentropic efficiency of the turbine if the exit pressure remains the same. D) Show process states on attached Mollier diagram. E) Give two reasons why exit entropy could be larger than inlet entropy. F) How does the isentropic efficiency relate to the power cycle efficiency?
