A heat engine consists of a compressor, a turbine, and two heat exchangers using air as the working fluid. The compressor is adiabatic with air entering at 300K and 100kPa, and exiting at 600 K and 800kPa. Then the air is heated isobarically in one of the exchangers by adding 950kj/kg of heat. Then the air expands while passing through the adiabatic turbine with an isentropi efficiency of 86% with a discharge pressure of 100kPa. Assume the air is a Calorically Imperfect Ideal Gas. Find work required by the compressor, isentropic efficienty of the compressor, work output of the turbine, net work produced by the system, and the device's thermal efficiency.
