Calculates the liquid specific volume as a function of pressure and temperature—all variables expressed in SI units. Only use for compressed water. An error of -1 (or input out of range digital state) returns for input temperature higher than the saturation temperature for the input pressure. However, the function computes for the full range of temperature for input pressure greater than the critical pressure.

Format

StmSI_VPTL(P, T)

Arguments

  • P

    Pressure of the water in kpa. The valid range is 0.6108 to 110316.0 kpa.Pressure of the water in KPa. The valid range is 0.611213 to 100000 KPa for temperatures up to 800 °C, and 0.611213 to 50000 Kpa for temperatures up to 2000 °C.

  • T

    Water temperature in °C. The valid range is 0 to 2000 °C.

Returns

Computed liquid specific volume in cc/g or Error digital state.
