Mechanical Engineering

air behaves as anideal gas with R = 0.287 k J k g K.

  1. A compressor operates at steady state and takes in air fromambient 0 kPa, gage and 300 K. The outlet pressure is 60 kPa, gageand 300 K. Determine:
    1. the mass flow rate if the inlet area is 10 cm2 andthe inlet pressure is -3 kPa, gage.
    2. the minimum outlet temperature that is possible for thiscompressor.
    3. the isentropic efficiency of the compressor, assuming no heatloss.
    4. if there is a heat loss of 20 kJ/kg, the work required to runthe compressor, and the new isentropic efficiency.

outlet is 500K
