2. Carbon dioxide is compressed steadily by a 5-kW compressor from 100 kPa and 17C to 600 kPa and 167C at a rate of 1.6 kg/min. During this process, some heat transfer takes place between the compressor and the surrounding medium at 17C. Determine; a) Heat lost (kw) b) Isentropic compressor work and efficiency (ASSUME CV AND CP CONSTANT.) c) The rate of entropy change during this process. d) The rate total (surroundings +compressor) entropy change of this process. Note: AStotal=ASsurr.+ASsyst >0. (entropy never decreases) R=0,1889, cp=0,846, cv=0,657, k=1,289 600 kPa 167C 17C ompressor 5kW 100 kPa 17C
