Abstract
Computer codes, SteamTables and SteamTablesIF97in VB. NET were written for the thermodynamic properties of pure water, using the formulations:IAPWS-95 for scientific use and IAPWS-IF97 for industrial use, respectively. The execution time for IAPWS-IF97 is in general 70 times less than that for IAPWS-95. The p and T accuracies for the both the formulations are within T=±0. 1 K and p=±0. 001 MPa. However, the steam tables contain thermodynamic inconsistencies, associated with the measurement errors of Cp near the liquid-vapor separation boundary. This causes limitation in the steam transport algorithm in a pipeline.
