Chapter 17, Problem 17150(choose chapter or problem)
Steam at 6.0 MPa and 700 K enters a converging nozzle with a negligible velocity. The nozzle throat area is 8 cm2 . Approximating the flow as isentropic, plot the exit pressure, the exit velocity, and the mass flow rate through the nozzle versus the back pressure Pb for 6.0 $ Pb $ 3.0 MPa. Treat the steam as an ideal gas with k 5 1.3, cp 5 1.872 kJ/kgK, and R 5 0.462 kJ/kgK.
