StmEng_TPH

Calculates the steam temperature as a function of pressure and enthalpy—all variables expressed in English units. Use for both superheated and wet steam.

Format

StmEng_TPH(P, H)

Arguments

• P

  Pressure of the steam in psia. The valid range is 0.08865 to 14503.77 psia..

• H

  Specific enthalpy of the steam in BTU/lbm. The valid range is -0.017879547 to 1744.60206 BTU/lbm.

Returns

Computed steam temperature in °F or Error digital state.

Sample Values

Note: Even if the input enthalpy is less than that of the saturated liquid, the function still returns the saturated temperature as the answer without setting an error state.
