Abstract:

WATER95 is an open source implementation of IAPWS95, the current standard formulation of the properties of water and steam for scientific use. It is written in MATLAB and is aimed primarily at educational use. Its value for teaching standard processes with water as a working medium is shown on the basis of worked exercises. They provide examples of isobaric and adiabatic processes and the calculation of the efficiency of the standard Clausius–Rankine cycle for steam turbines, and show how to extend the package for the computation of processes of constant enthalpy. Finally the advantages and drawbacks of using the package in a thermodynamics course are discussed.

Keywords: IAPWS95; TEACHING THERMODYNAMICS; WATER AND STEAM PROPERTIES
