kJFor these problems, assume air behaves as an ideal gas with R = 0.287kg K 1. A compressor operates at steady state and takes in air from ambient 0 kPa,

gauge and 300 K. The outlet pressure is 50 kPa, gauge and 400 K. Determine: A. the mass flow rate if the inlet area is 10 cm2 and the inlet pressure is -2 kPa, gauge. B. the minimum outlet temperature that is possible for this compressor. C. the isentropic efficiency of the compressor, assuming no heat loss. D. if there is a heat loss of 30 kJ/kg, the work required to run the compressor, and the new isentropic efficiency.
