Q3. Steam at 260 °℃ and 7 bar absolute is expanded through a nozzle to 200 °C and 4 bar. Negligible heat is transferred
Q3. Steam at 260 °℃ and 7 bar absolute is expanded through a nozzle to 200 °C and 4 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 °℃ and 4 bar. Use the open-system energy balance to calculate the exit steam velocity. [5 Marks]
