Air Properties At Pressure & Temperature

08/07/2008 2:03 AM

Hi,

I am looking for equations and/or excel add-on to estimate air properties i.e. density, viscosity, enthalpy, entropy, at pressure and temperature

Example : What is the density of dry air and wet air at 5 barg and 50 degC ?


Thanks in advance.

PWSlack, Ried & BudT,

Thanks and appreciate for your inputs.

I'm working on some studies with excel program which required generation of air properties for rigorous calculation.

I will looks into these website.
