ABSTRACT:
A simple and accurate method for determining the enthalpy of wet steam using pressure and moisture content values. Moisture content is determined by measuring sonic velocity of the steam, which is dependent upon enthalpy. A small sample of the wet steam is superheated by pressure reduction to a single-phase state prior to measuring its sonic velocity in order to achieve greater accuracy of this measurement. From its sonic velocity, enthalpy of the sample is calculated. Since the process takes place at constant enthalpy, the enthalpy value of the sample is the same as that of the fluid from which it was drawn.
