Steam at 260°c and 7.00 bar absolute is expanded through a nozzle to 200°c 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 kj/kg at 260°c and 7 bar and 2860 kj/kg at 200°c and 4 bar. use the open-system energy balance to calculate the exit steam velocity
