Air properties at high altitudes

Air properties at high altitudes

Air properties at high altitudes

(OP)
I would like to get air properties such as dynimic viscosity, specific heat, thermal conductivity as well as density at high altitudes. Will you suggest any text, calculator or any other information in which I can obtain those properties at various altitudes?

RE: Air properties at high altitudes

wouldn't it be possible to use a standard composition of air in a process simulation environment (aspen, simsci, whatever)and to calculate the properties at conditions below 1.013 bar abs, i.e. vary the pressure?

hth,
chris
