Air is compressed by a compressor from v1 = 1.0 m3/kg to v2 = 0.71 m3/kg in a reversible, isothermal process. the air temperature is maintained constant at 25 oc during this process as a result of heat transfer to the surroundings. air moves through the compressor at a rate of m = 1 kg/s. a)- determine the entropy change of the air per kg of air. b)- what is the power required by the compressor? c)- what is the rate at which entropy leave the compressor?
