Yisuanbao app – Basic calculations – Property calculations – Software for calculating the properties of water and water vapor (IF97). Development basis: The IAPWS 1997 formulation for calculating the thermodynamic properties of water and water vapor used in industrial applications, published by the International Association for the Properties of Water and Steam in Iringhausen, Germany, in September 1997. During development, the IAPWS-IF97 formula is strictly followed, along with comprehensive testing and verification. At the same time, experts in the industry are welcome to offer their valuable suggestions to jointly promote the development of engineering technology in our country. By default, the International System of Units is used, with temperature measured in degrees Celsius. Function description: User input: 1. Pressure, temperature ； 2. Pressure, specific entropy ； 3. Pressure, specific enthalpy ； 4. Specific enthalpy, specific entropy ； Calculations can be performed using any one of the four sets of data. The calculation results include: (1) the region to which water or water vapor belongs; (2) pressure, temperature, specific enthalpy, specific entropy, specific volume; (3) sound speed, dielectric constant, dynamic viscosity, Prandtl number, internal energy, specific heat at constant pressure, specific heat at constant volume, and thermal conductivity.
