Steam at 260C and 7.00 bar absolute is expanded through a

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 2974kJ/kg at 260C and 7.00 bar and 2860kJ/kg at 200C and 4.00 bar. Use the open system energy balance to calculate the exit speed of the steam. u0=m/s
