Area of phase state

To process this page used the WaterSteamPro function "wspPHASESTATEPT": area of phase state as function of pressure p [Pa], temperature t [K].

Function returns code of phase state in point with given p, t. If pressure p or temperature t are above critical (Prk or Tkr), the result is "3" (phase state - supercritical). If the point is situated above the saturation line (in P-T diagramm) the result is "1" (phase state - liquid). If the point is situated below the saturation line (in P-T diagram) the result is "2" (phase state - steam). If point is situated below triple point, the return is error value ("-1").
