The air is passed through a heat exchanger after compression and cooled to its original condition entering into the air jet. The pressure loss in heat exchanger is 0.1 bar. the pressure of air leaving the cooling turbine is 1.013 bar and is also the pressure in the cockpit. the cooling load in the cockpit is 70kW. Determine i)Mass flow rate of air circulated to the cabin. ii)Net power delivered to the refrigeration system. iii)The COP of the system.
