A steam power plant operates with a high pressure of 5 MPa and has a boiler exit temperature of 600 C receiving heat from a 700 C source. The ambient at 20 C provides cooling for the condenser so it can maintain 45C inside. All the components are ideal except for the turbine which has an exit state with a quality of 97%. Find the work and heat transfer in all components per kg water and the turbine isentropic efficiency. Find the rate of entropy generation per kg water in the boiler/heat source setup.
