Flow through a Venturi 16-3
In another paper I gave you the formula for computing the approximate flow through an orifice or nozzle. Here is the formula for an approximate flow through a venturi tube.
For any venturi tube use:
Or you can use:
Q = flow, in gpm
d1= diameter of venturi throat, inches
d2 = diameter of main pipe, inches
H = difference in head between upstream end and throat.
These formulas will work for any liquid with a viscosity similar to water.
