Abstract : A FORTRAN 77 program is given with which thermodynamic properties for liquid and gaseous states for water can be calculated for the temperature and pressure range, 250 less than or equal to T(K) less than or equal to 4000 and 0 less than or equal to P less than or equal to Pmax, where Pmax is the lesser of the pressure of melting ice or 4 G Pa (40,000 bar). The program yields values for enthalpy, entropy, heat capacity, speed of sound, Joule-Thomson Coefficient, second virial coefficient, isothermal compressibility coefficient, coefficient of thermal expansion, and PpT relations that are everywhere in accord with accurate data for water. Included is a brief outline of the derivation of the equations. (Author)
