For a project for petrol vapour recovery, is the viscosity of ethanol / methanol vapour much different from petrol vapour? Does anyone have viscosity data for these three gaseous fuels?
Thanks for that - I have seen a lot of hydrocarbon gases are around the 0.007 centipoise figure. Why then does air, also a gas, have more than double the viscosity (0.018 centipoise)? Is it dependant on molar mass?
