5-32 Steam at 5 MPa and 400°C enters a nozzle steadily with a velocity of 80 m/s, and it leaves at 2 MPa and 300°C. The inlet area of the nozzle is 50 cm2, and heat is being lost at a rate of 120 kJ/s. Determine a) the mass flow rate of the steam, b) the exit velocity of the steam, and c) the exit area of the nozzle. | |
