1. A reciprocating compressor delivers 0.10kg/s of air at a pressure of 12 bar, the air
enters the compressor at 1 bar and 150C. Calculate the delivering temperature of the
air, the work transfer rate in the compression process, and the heat transfer for:
a) A reversible polytropic process, 𝑃𝑉
1.2 = 𝑐𝑜𝑛𝑠𝑡𝑎𝑛𝑡 (436 K, -21050 W)
b) A reversible adiabatic process
c) A reversible isothermal process. (288 K, -20550.2 W)
(Assume air is a perfect gas with 𝑐𝑝 = 1.005𝑘𝐽𝑘𝑔−1𝐾
−1
and 𝛾 = 1.4)
