The databases include both thermodynamic surfaces and representations for transport properties over broad ranges of temperature. pressure, and composition. We also discuss our current research to improve the standards for air and for aqueous systems including the binary mixture of ammonia and water....

Description Below see the figure, where two fluids are edged in red, the composition differs only in the presence of 0.5% water ("Fluid 1 Simple" and "Fluid 1 Simple with water"). But the properties differ significantly. For example, the...

5. Now open any EXCEL spreadsheet, go to any cell and type something like: =density("water","TP","SI",500,100) 6. If you need to edit the .xla file after it has been installed, reopen the REFPROP.xls file, edit the VB section, then save it as .xls. Under 'Tools' go to ...
The LFPG is an extremely stable, well-characterized source of humidity whose output is based on invariant thermodynamic properties of water. The expanded uncertainty (k=2) of the LFPG is 0.8% water vapor mole fraction. This document describes a new calibration service for water permeation tubes....

Rather than using commonly employed gravimetric methods for permeation-tube calibration, the method applied here links the permeation rate of the permeation tube to the thermodynamic properties of ice. Using a hygrometer based on cavity ringdown spectroscopy, we compare the water vapor concentrations ...
