A special computer program has been developed, using QBASIC, to calculate numerically the thermodynamic changes of an ammonia-water vapor mixture along an isentropic expansion. The thermodynamic relations used were obtained in terms of the Gibbs' free energy equation for the gas phase of pure components and the entropy was held constant with an accuracy better than 0·000001 kJ/kg K. Results are in the form of tables allowing further processing by spreadsheet software such as Excel, Works or Lotus in order to obtain them in diagram form. Copyright © 1996.
