Mechanical EngineeringQ&A LibraryAir enters a compressor steadily at the ambient conditions of 100kPa and 20 degrees celcius and leaves at 900 kPa. Heat is lost from the compressor in the amount of 150kJ/kg and the air experiences an entropy decrease of 0.50kJ/kg*K. Using constant specific heats, determine (a) air exit temperature, (b) work input to the compressor, and (c) entropy generation during the process.Question
