To process this page used the WaterSteamPro function "wspWEXPANSIONPTPEFF": sound velocity at the end of expansion/compression process [m/sec] as function of pressure at initial point p0 [Pa], temperature at initial point t0 [K], pressure at final point p1 [Pa], internal efficiency of process eff [-].

It is a function. The range of the validity is within that described in IF-97. Function returns a parameter at the end of the expansion process from initial point with arguments p0, t0 to pressure p1 with relative efficiency eff. The process is calculated by the formula: h1 = h0 - eff * (h0 - h1isoent), where h0 - specific enthalpy in initial point, h1 - specific enthalpy in finite point of the expansion, eff - efficiency, h1isoentr - specific enthalpy in finite point at isoentropic equilibrium expansion (s = Const). For compression process calculation it is necessary to use the value inverse to the efficiency eff (i.e. 1/eff). Since at some stages the function use iterations, to speed up calculations you may disable precision mode (functions wspGETTOLERANCEMODE and wspSETTOLERANCEMODE) or vary relative precision for internal iterations (functions wspGETTOLERANCE and wspSETTOLERANCE).
