水和水蒸气性质计算程序WaterPro7.0采用国际公认的《工业用1967年IFC公式》和《工业用1997年IAPWS公式》进行计算，计算结果在相应版本国际水蒸气热力性质骨架表的允差范围内。

程序能根据压力、温度、焓、熵、比容五个参数(有时加上干度参数)中的任意两个参数，求出相关的15个水蒸汽参数，如定压比热、定容比热、内能、音速、定熵指数、动力粘度、运动粘度、导热系数、普朗特数、介电常数、当给定波长为0.226500 μm时折射率，等等。

-Water and steam properties calculation program WaterPro7.0 adoption of internationally recognized the　industrial 1967 IFC formula　and　industrial 1997 IAPWS formulas　calculate calculated results in the corresponding version of the steam thermodynamic properties of skeleton table of the status of the poor range.



Program according to the five parameters such as pressure, temperature, enthalpy, entropy, specific volume (sometimes with dry degree parameter) of any two parameters for 15 related to a steam parameters, such as constant pressure specific heat and constant volume specific heat, internal energy, speed, entropy index, dynamic viscosity and kinematic viscosity, heat conduction coefficient, Prandtl number, dielectric electric constant, when the certain wavelength is 0.226500 m refraction rate, and so on.
