Problem 3. - Hot gases enter a jet engine turbine with a velocity of 50 m/s, a temperature of 1200 K, 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 constant specific heats (mean molecular mass 25, y = 1.37). Find the turbine power output in kJ/(kg of mass flowing through the turbine). Problem 4. - Determine the force F required to push the flat plate against the round air jet with a velocity of 10 cm/s. The air jet velocity is 120 cm/s, with a jet diameter of 7.0 cm. Air density is 1.2 kg/m3. F
