A cogeneration plant on the cylce shown below. For the purpose of this problem the gas can be considered to be Air. If you cant see the problem heres a link Compressor isentropic efficiency 85% Gas turbine expansion ratio 10:1 Gas turbine isentropic efficiency74% Steam turbine isentropic efficiency 82% Pump work negligible find the properties at each state in the process but how do I do part A and B knowing all the Values. What is the overall efficiency of the cycle? What is the ratio of gas mass flow rate to steam flow rate?
