Compressed Air Leak into a Liquid
Compressed Air Leak into a Liquid
(OP)
Does anybody know how to calculate the CFM on a compressed air leak when the air is not blowing into the atmosphere but into a liquid like the pickling acid?
I am trying to replace a compressed air bubble-system agitator with an energy efficient eductor in a tank mixing application. However, I do not know how to estimate the amount of air that is currently being blown through the agitator. I know that the agitator is currently blowing compressed air from a 1/8” pipe, and the CA line pressure is 95 psig. I do not know the density or the temperature of the acid being mixed but I can easily get that information if I find some use for it. Is there an equation for CA leaks that deals with the situation of leaks underwater or other liquids?
Please help

If the air pressure is 95 psig inside the line and it's discharging to the static head inside a tank, you are almost certainly have choked flow through the orifice (dP/Pinlet > 0.5 where Pinlet is the absolute pressure). If you do have choked flow, the static head in the tank is not going to affect the flow rate.
