Mathematical Modeling of Water Properties

Abstract

Mathematical models describing physical water property data are presented. These models define each of the following water properties as a function of the water temperature. The water property models developed include the specific weight, density, modulus of elasticity, dynamic viscosity, kinematic viscosity, surface tension and vapor pressure. Along with each model, the actual data and calculated values are presented for comparison. The method of least squares fit, which was used to model each set of data, is reviewed. The source of FORTRAN computer program used to generate the equations can be obtained from the Lenox Institute of Water Technology.
