Air enters a compressor at 650 oC and 400 kPa and exits at 900
oC and 800 kPa. The compressor
is not well insulated and loses heat to the surroundings at a rate
of 20 kJ/kg. Find the specific
work of the compressor and the exergy destroyed for the process.
Surroundings are at 25 oC.
(Use an appropriate average specific heat for the calculations.)

5. Air enters a compressor at 650 °C and 400 kPa and exits at 900 °C and 800 kPa. The compressor is not well insulated and loses heat to the surroundings at a rate of 20 kJ/kg. Find the specific work of the compressor and the exergy destroyed for the process. Surroundings are at 25 °C. (Use an appropriate average specific heat for the calculations.) w = -277 kJ/kg S gen =.11 kJ/(kg.K) ex destroyed = To s gen = (25+273) (.11) J/kg
oC and 800 kPa. The compressor
is not well insulated and loses heat to the surroundings at a rate
of 20 kJ/kg. Find the specific
work of the compressor and the exergy destroyed for the process.
Surroundings are at 25 oC.
