Hi all,

Consider that ambient air at normal atmospheric pressure, at 25 degrees celcius and 50% humidity contains 12 torr of watervapour.....

Now we could make a calculation:

Stan descripes how much water his buggy needed for running.

How much watervapour = equal to this amount of water?

How much air goes thru an engine when idle?
