Steam at 260°C and 7 bar absolute pressure is expanded through a nozzle to 200°C and 4 bar. Neglig ible heat is transferred from the nozzle to its surroundings. The inlet velocity of the steam is negligible. The specific enthalpy of the steam is 2974 at 260°C and 7 bar and 2860 kJ/kg at 200°c and 4 bar. write the exit steam velocity using open system energy balance
