Steam enters an insulated nozzle at 1.0 MPa and 400°C, at a velocity of 3 m/s. For an exit pressure of 400 kPa, using your model for a nozzle, plot the exit velocity for exit temperatures ranging from 280°C to 380°C.

Given: Steam, P1 = 1.0 MPa, T1 = 400°C; V1 = 3 m/s; P2 = 400 kPa
Insulated, so assume, Q?=0


For a nozzle, assume steady –state, steady-flow single-inlet, single-outlet flow, and assume that W?=?pe=0

These assumptions result in the first law being (State 1 is inlet, State 2 is outlet)



Take h1 = 3264.39 kJ/kg
