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.

Transcribed Image Text: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.
