Question
Air enters a compressor steadily at the ambient conditions
of 100 kPa and 22C and leaves at 800 kPa. Heat is
lost from the compressor in the amount of 120 kJ/kg and the
air experiences an entropy decrease of 0.40 kJ/kgK. Using
constant specific heats, determine (a) the exit temperature
of the air, (b) the work input to the compressor, and (c) the
entropy generation during this process.
