Consider an ideal Ericsson cycle with air as the working fluid executed in a steady-flow system. Air is at 27°C and 120 kPa at the beginning of the isothermal compression process, during which 150 kJ/kg of heat is rejected. Heat transfer to air occurs at 1200 K. Determine (a) The maximum pressure in the cycle,
(b) The net work output per unit mass of air, and
(c) The thermal efficiency of the cycle.
