A Brayton cycle is used to produce power. Air flowing at 40 lbm/s enters the compressor at one atmosphere and 60°F and exits the compressor at 10 atmospheres. The compressor isentropic efficiency is 80%. The air is then combusted with fuel such that the turbine inlet temperature is 2200°F. The turbine isentropic efficiency is 85%. Using the "constant specific heats" method, and assuming air properties for the combustion gas which has the same flow rate as the air entering the compressor, determine the following: The compressor outlet temperature, The compressor power consumed, The turbine outlet temperature, The turbine power produced, The net power (in megawatts), and The thermodynamic efficiency of the cycle.

Biomass is used as fuel to power the following cogeneration plant on a school. The turbine drives an electric generator to produce electricity, and part of the steam is extracted to provide heating to campus buildings. The boiler provides 106 kg/h of steam at 6 MPa, 520 °C, of which 4x105 kg/h is extracted between the first and second turbine stages at 1 MPa and diverted to the building heating load. Condensate returns from the building heating load at 0.95 MPa, 115 °C, and it is mixed with liquid exiting the lower pressure pump at 0.95 MPa. The entire flow is then pumped to the boiler pressure. Saturated liquid at 6 kPa leaves the condenser. The turbine stages and the pumps operate with isentropic efficiencies of 89 and 85%, respectively. The efficiency of the electric generator is 93% for converting turbine mechanical power into electricity. Calculate the heating load in kJ/h. Calculate the electric power generated in MWe.
