    Formula for temperature change of liquid through a valve

    For clarification, the pressure drop across the valve can be between 150 to 500 bar at flow rates between 150-1500 m3/hr. We have observed/measured a temperature rise across the valve before but ask if there is a calculation available to enable us to predict the rise.

    Formula for temperature change of liquid through a valve

    How do I calculate the temperature rise (or fall) of a liquid as it passes through a valve knowing the media (i.e. water), media density/specific heat, flow rate thru' valve, valve inlet temperature and valve inlet pressure plus pressure drop.
