1. During a reversible process 320 kJ/s of heat are given off by 1.5 kg m /s of a certain gas while its temperature remains constant at 27.7 o C. For this gas c p = 2.232 kJ/kg m - o K and k = 1.303. The initial pressure is 590 kPaa. Find a) final volume, b) work non flow (kJ/s), c) ∆S (kJ/ o K -s) 2. An ideal compressor compresses 12 kg/min of air isothermally from 99 kPaa and a specific volume of 0.81 m 3 /kg m to a final pressure of 600 kPaa. Determine a) Power (kW) required to drive the compressor, b) change in entropy (kJ/ O K), c) heat transferred.
