1. The products of combustion of a jet engine leave the engine with a velocity relative to the plane of 500 m/s, a temperature of 525?C, and a pressure of 75 kPa. Assuming that k = 1.32, Cp = 1.15 kJ/kg K for the products, determine the stagnation pressure and temperature of the products relative to the airplane.
2. Steam is flowing to a nozzle with a pressure of 400 kPa. The stagnation pressure and temperature are measured to be 600 kPa and 350?C. What are the flow velocity and temperature?
