Abstract : The THERMOSPLINE program was developed in an attempt to obtain a single mathematical formulation of the thermodynamic properties of water and steam in the pressure range from 0 to 100 bar and temperature range from 0 to 800C. The program applies the spline function method to fit the sparse data given in the 1963 International Skeleton Tables of the Thermodynamic Properties of Water Substance. However, this input data may be replaced by any new set of experimental data on steam or indeed by data on any pure substance. This capability may lead to additional applications of the method since tables of thermodynamic properties exist for very few substances. The thermodynamic principles involved in this investigation are presented, followed by a detailed description of the program and a summary of the computer experiments performed. (Author)
