About
The thermophysical properties of air are calculated from polynomial curve fits to a data set for 100K to 1600K in the SFPE Handbook of Fire Protection Engineering 2nd Edition Table B2. Therefore, the property infromation is valid in the range of 100K to 1600K. Plots of the data set with the bestfit curve,
the equation of the bestfit curve and it's R^{2} value, and error analysis of the curve fit with respect the measured values have been performed.
