Steam at 260C and 7.00bar absolute is expanded through a nozzle to 200C and 4.00bar. Negligible heat
Question:
Steam at 260°C and 7.00bar absolute is expanded through a nozzle to 200°C and 4.00bar. Negligible heat is transferred from the nozzle to its surroundings. The approach velocity of the steam is negligible. The specific enthalpy of steam is 2974J/kg at 260°C and 7bar and 2860kJ/kg at 200°C and 4bar. Use the open-system energy balance to calculate the exit steam velocity.
