Colin Mill Posted August 13, 2007 Share Posted August 13, 2007 A few figures to contemplate:- Density@STP: Air 1.293 kg/cu.m N2 1.25kg/cu.m Spec. heat capacity: Air 993J/kg/K N2 1040J/kg/K Cp/Cv Air 1.402 N2 1.404 Viscosity Air 18.3E-6 N.s/m2 N2 16.7E-6 N.s/m2 One thing to bear in mind regarding water vapour is that air delivered from a cool air reservoir of a garage compressor at typically 150psi is quite dry ( less than 2g/m3 or a dew point of less than -10degC) Link to comment Share on other sites More sharing options...
