Re: How wide are KM downstems?
So you are limited by the volumetric efficiency of the smallest hole right?
And stem size isnt the same as how tall a hookah is right? But i guess it would be an "ok" assumption to make as long as you take both as the same. I think we should note though that if you have a short downstem that doesnt go that deep into the base, then you cant assume your "29inch" whatever is going to perform like a 29" KM or whatever that has a longer downstem.
