1. Steam at 0.6 MPa and 200 °C enters an insulated nozzle with a velocity of 50 m/s, as shown in below figure. It leaves at a pressure of 0.15 MPa and a velocity of 600 m/s. Determine the final temperature if the steam is superheated in the final state and the quality if it is saturated. V₁ = 50 m/s P = 0.6 MPa T₁ = = 200°C Control surface = 600 m/s = 0.15 MPa P₁ =
