A gas turbine system operates with air entering at a velocity of 115m/s and a denisty of 1.25kg/m3 . The gas turbine inlet area is 0.05m2. Air leaves the turbine at a velocity of 135m/s and a density of 0.70kg/m3. The specific enthalpy of theair is reduced by 160kJ/Kg as it passes through the turbine and the air is estimated to looose heat at a rate of 30kJ/KG during process
