Water vapor at 100 lbf/in^2, 500 degrees F and a velocity of 100 ft/s enters a nozzle operating at steady state and expands adiabatically to the exit, where the pressure is 40 lbf/in^2. If the isentropic nozzle efficiency is 95%, determine for the nozzle (a) the velocity of the steam at the exit, in ft/s and (b) the amount of entropy produced, in Btu/degree R per lb of steam flowing.
