Chapter 7, Problem 7.22(choose chapter or problem)
Steam at 260C and 7.00 bar absolute is expanded through a nozzle to 200C and 4.00 bar. Negligible heat is transferred from the nozzle to its surroundings. The approach velocity of the steam is negligible. The specific enthalpy of steam is 2974 J/kg at 260C and 7 bar and 2860 kJ/kg at 200C and 4 bar. Use the open-system energy balance to calculate the exit steam velocity.
