Please help solve and include all calculations/analysis, thank you. A cogeneration plant operates on the cycle shown. For the purpose of this problem, the gas can be considered to be air. compressor isentropic efficiency gas turbine expansion ratio 85% 10:1 gas turbine isentropic efficiency 74% steam turbine isentropic efficiency 82% pump work negligible combustor 2240°F 150 psia gas turbine 2 3 compressor 4 7 100 psia 440°F steam turbine waste 14.7 psia 60°F heat boiler 8 30 psia 6 400°F 100 psia 250°F 5 condenser pump (a) What is the overall efficiency of this cycle? (b) What is the ratio of steam mass flow rate to gas mass flow rate?
