nitrogen is compressed in an axial-flow compressor operating at steady state from a pressure of 15 lbf/in.2 and a temperature of 50 of to a pressure 60 lbf/in.2. the gas enters the compressor through a 6-in.-diameter duct with a velocity of 30 ft/s and exit at 198 of with a velocity of 80 ft/s. using the ideal gas model, and neglecting stray heat transfer and potential energy effects, determine the compressor power input, in hp
