Determine energy per mass developed if air enters a device
Air enters a device operating at steady state at 10 bar and 580 K, and leaves at 1 bar and 500 K. The rate of heat transfer to the air is 347 kJ/kg. Neglecting kinetic and potential energy effects, determine the energy per mass developed in kJ/kg.
