I think the pressure drop due to the keg/faucet would probably have to be modeled numerically. They aren’t complex arrangements compared to, say, a nuclear reactor core, but I don’t think they could be accurately modeled as arrangements of sections of smooth pipe either, so lookup tables are probably out. As far as flow rate, you’re right that it’s recursive and would also likely have to be solved for numerically. In reality, I just used a graduated cylinder (or pint glass, for that matter) and a stopwatch.

I have two questions though.

First, how do you find out what is the pressure drop due to the keg and faucet?

Second, how do you know what the flow rate would be? Won’t the flow rate be a function of the pressure drop itself, which is again a function of the flow rate?

Thanks in advance.
