Consider 5.0 pounds per minute of water vapor at 10O Ib;/in², 500°F, and a velocity of 100 ft/s entering a nozzle operating at steady state and expanding adiabatically to the exit, where the pressure is 40 Ibf/in?. The isentropic nozzle efficiency is 85.0%. Determine the velocity of the steam at the exit, in ft/s, and the rate of entropy production, in Btu/min-°R.
