heal.abstract	For the analysis of thermodynamic cycles, processes, or high speed flow problems involving steam, the isentropic and isenthalpic changes in properties are often used for computing or simulating purposes. The use of the detailed but long and computer time-intensive procedures is in many cases not acceptable and there is a need for some approximate but fast procedures. The present paper presents such an algorithm for computing the state variables of steam during isentropic or isenthalpic changes in a fraction of a second, even with personal computers. Extensive runs of the exact steam equations yielded results that afterwards were correlated using suitable algebraic relations. The corresponding coefficients of these expressions have been cross-correlated and two relations giving the compressibility factor during state changes at constant entropy and constant enthalpy have been obtained.	en
