To process this page used the WSP function "wspDDDPHPT": derivate of density on pressure with constant enthalpy of water/steam [sec2/m2] as function of pressure p [Pa], temperature t [K].
The range of the validity is within that described in IF-97. The function wspWATERSTATEAREA2 is used to determine the IF-97 region. Then the necessary function (wspDDDPHxPT) is used.
