Water Vapor Property Calculator

This tool calculates thermophysical properties of water vapor for 380K < T < 850K.

About

The thermophysical properties of water vapor are calculated from best-fit curves for a data set of 380K to 850K in the SFPE Handbook of Fire Protection Engineering 2nd Edition Table B-2. Therefore, the property information is valid in the range of 380K to 850K. Plots of the data set with the best-fit curve, the equation of the best-fit curve and it's R² value, and error analysis of the curve fit with respect the measured values have been performed.

Density: Plot with curve fit.
Error: Max= -0.28%, Average= 0.12%
Specific Heat: Plot with curve fit.
Error: Max= 0.44%, Average= 0.16%
Thermal Conductivity: Plot with curve fit
Error: Max= 0.06%, Average= 0.04%

Temperature:	K

Density =		kg/m³
Specific heat =		Ws/kgK
