Do not post a solution unless you get 372 m/s for A. I have asked this question several times and people keep posting incorrect solutions. A is 372 m/s.

Problem 2: Steam enters an insulated nozzle at 300 kPa and 300C and leaves at 175 kPa and 150C. The inlet diameter is 50% larger than the outlet diameter, i.e., D = 1.5D2 (a) Determine the exit velocity of the steam if the inlet velocity is 120m/s. (6) Explain the decrease in pressure at the nozzle outlet in terms of conservation of energy principle. D. 300 kPa 300C V Steam D. 175k Pa 150C V Answer: a) 372m/s
