total head specific enthalpy
1. In a steam nozzle, steam enters with negligible velocity with a specific enthalpy of 2840 kJ/kg and leaves with a specific enthalpy of 2780 kJ/kg. Calculate the velocity of steam leaving the nozzle.
2. Steam has a specific enthalpy of 2800 kJ/kg and a velocity of 120 m/s. What is its total head specific enthalpy?
