Calculating the effect of humidity volume and temp of compressed air

[QUOTE="Chestermiller, post: 4636636, member: 345636"] You pretty much do it the same thing as for dry air, except you use a slightly different value of k. If you know the relative humidity and the temperature, then you know the mole fraction of water vapor in the gas phase, correct. If you know the mole fraction of water vapor x, then you can calculate the weighted average molar heat capacity at constant volume C[SUB]v[/SUB] (weighted by the mole fractions of air and water vapor). The weighted average heat capacity at constant pressure is obtained by adding R. Then you can calculate k for the moist air. If at any point you need to use the ideal gas law, you need to use a molar weighted average of the molecular weight. [/QUOTE]
