Air is saturated (air with water in it)
T = 40C
P = 3 bar
i need to work out the density of this vapour, now is the vapour the air with the water or just the water?
is the solution a simple rearrange of the ideal gas law
n/V = P/RT
m/V = PMv/ RT (Mv is molecular weight of water or air? Do i average the two? not sure about this)
Or is it down the road of humidity?
Any help greatly appreciated, even a prod in the right direction is fab
Who do you think it is...
