Hi guys! Just want to ask if anyone has found a work around in computing enthalpy using Temperature and quality. The excel formula is StmTQH(Temperature,Quality,Unit Set).

With PI AF only Stm_HPX is available sadly there is no Stm_TPX. as Stm_HPX is equivalent to StmPQH in excel.

Please Help.

Hello Ricky: If I understand the issue, you wish to calculate the enthalpy of saturated steam given the saturation temperature and the quality. Since the steam is saturated, the state should be defined by either the saturation temperature or the saturation pressure. Therefore, since you have the saturation temperature, the corresponding saturation pressure can be determined using Steam_PsatT inside AF Analytics. Then the resultant Psat could be used with your quality to calculate the enthalpy using Steam_HPX. It is one more step but may provide a workable solution. Please let me know what you think and if this works for you.

Thanks!
