An iden insulated gas compressor real gas mixture consisting of 15% h2, 40% n2, and 45% co2, by mass. the gas mixture enters at a temperature of 17ºc and a pressure of 100 kpa, and exits at a pressure of 1200 kpa. the mass flow rate of the mixture is 2.5 kg/s. assuming that the gas mixture has constant specific heats, determine the exit temperature and power consumed if (a) the compressor is isentropic and (b) the compressor has an isentropic efficiency of 0.78.
