Question: Consider an ideal Ericsson cycle with air as working fluid executed in a steady-flow system. Air is at 30oC and 115 kPa at the beginning

Consider an ideal Ericsson cycle with air as working fluid executed in a steady-flow system. Air is at 30oC and 115 kPa at the beginning of the isothermal compression process during which 155 kJ/kg of heat is rejected. Heat transfer to air occurs at 1250 K. Determine
(a) The maximum pressure in the cycle,
(b) The net work output per unit mass (wnet) of air and
(c) The thermal efficiency (ηth) of the cycle. Use the PG model.
