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.

C6 6.

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.
Step 1
* Your answer is incorrect.
Determine the velocity of the steam at the exit, in ft/s.
Hint
