A closed system consisting of 0.5 m3 of air at 35°C, 1 bar, and 70% relative humidity is cooled at constant pressure to 29°C. Determine: a. The mass of the air and the mass of the water vapor b. The work for the process c. The heat transfer for the process

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
