Hi All,

Can any one please tell me what will be the value of Sutherland's constant for Steam to calculate Viscosity and Thermal Conductivity based on Sutherland's equation.

Thanks in advance AP

I've just had to calculate this too. I pulled out my Cranes and it only lists the gases listed on this page: http://www.lmnoeng.com/Flow/GasViscosity.htm But using this page: http://www.engineeringtoolbox.com/st...ity-d_770.html I backcalculated a Sutherlands by just using trial and error to about 1100. It will duplicate the numbers in that large viscosity graph to 2 sig figs.
