ericsson cycle
Consider an ideal Ericsson cycle with air as the working fluid executed in a steady-flow system. Air is at a temperature of 270 degrees and a pressure of 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 a temperature of 1200K. Determine
(a) the maximum pressure in the cycle
(b) the network output per unit mass of air
(c) the thermal efficiency of the cycle
