A New Equation of State for Compressed Water up to 1000 bar and up to 350°C

抄録

A new equation of state for compressed water was formulated in the ranges of temperatures from 0 to 350°C and of pressures from nearly zero to 1000 bar based on the International Skeleton Tables (1963). This new equation expresses the specific volume as the function of pressure and temperature, and is suitable for computer calculation. Calculated values of the specific volume and the enthalpy agree well with the values of the International Skeleton Table (1963). This new equation was transformed into the nondimensional canonical form (the equation of Gibbs function). The equations for various properties such as enthalpy, entropy and specific heat were derived from this new equation of state.
