An air cycle is executed in a piston-cylinder and is composed of the following 4 processes: 1-2 Adiabatic compression from 100kPa and 22C to 600kPa 2-3Addition of heat at constant volume up to 1500K 3-4Adiabatic expansion up to 100kPa 4-1Constant heat rejection to initial state Determine Q and W for each stage of the cycle in kj/kg. Use constant specific heats of 300K
