Hot gases enter a well-insulated jet engine turbine with a velocity of 50 m/s, a temperature of 1000oC, and a pressure of 600 kPa. The gases exit the turbine at a pressure of 250 kPa and a velocity of 75 m/s. Assume isentropic steady flow and that the hot gases behave as a perfect gas with mean molar mass of 25 and specific heat ratio of 1.38.
Find the turbine power per unit mass of the working fluid.
