Question details

Problem 7.040 SI Air enters a compressor operating at steady state at T, 320 K, P1-2 bar with a velocity of 80 m/s. At the exit, T2 675 K,P2-10 bar and the velocity is 180 m/s. The air can be modeled as an ideal gas with Cp 1.01 kJ/kg . K. Stray heat transfer can be ignored. Let To = 300 κ. Po = 1 bar. Ignore the effects of motion and gravity Determine, in kJ per kg of air flowing,: (a) the magnitude of the power required by the compressor (b) the rate of exergy destruction within the compressor,
