I have a vessel, that is open to pressurized air on one side, and on the other open to atmosphere via a tube. I need to know how can i determine at what rate liters/min can I put air through this vessel and the concentration of a vapor from a liquid below remain constant. So I have lets say ammonia in the liquid below, I allow the space above the liquid to reach equilibrium. I want to determine at what rate does the ammonia vaporize so I can determine the maximum flow I can put through the bottle and keep the concentration of the vapor in the air the same for about 30 minutes. I know I have to use the vapor pressure, molecular weight, surface area, temperature, and so forth. The 3 methods of determining rate of evaporation from this forum was a huge help, but they required the air flow above the liquid.
In short, at what rate does the vapor replenish itself in the headspace of the bottle?
