During a steady flow process air (an ideal gas with constant specific heats) goes from 27C, 1.3 bars to 2.7 bars. During this process work is input in the amount 64.4 kJ/kg and a heat loss of 14 kJ/kg occurs. The heat loss is passed to the surroundings which is at 27 C. a. Determine the change in entropy of the air passing through the device. b. is the process reversible?
