7-120 Air enters a compressor steadily at the ambient conditions of 100 kPa and 22°C 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/kg . K. 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. | |
