Consider 4.8 pounds per minute of water vapor at 100 lb/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 lb/in2. The isentropic nozzle efficiency is 95.0%. Determine the velocity of the steam at the exit, in ft/s, and the rate of entropy production, in Btu/min.°R.

Question
Consider 4.8 pounds per minute of water vapor at 100 lbf/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 lbf/in². The isentropic nozzle efficiency is 95.0%.
Determine the velocity of the steam at the exit, in ft/s, and the rate of entropy production, in Btu/min.°R.
Step 1
