A venturi has a large section diameter of 4', where the velocity V1=20ft/sec. The pressure difference between this section and throat, (P1-P2) = 25 psi. If the fluid is sea water (Sg=1.03) what is the diameter of the throat? Use figure #3 attached.© BrainMass Inc. brainmass.com September 28, 2022, 10:26 pm ad1c9bdddf
P1 - P2 = 25 psi = 25*32*144 lb.(ft/s^2)/ft^2 = 25*32*144 lb/ft.s^2
D1 = 4 in
D2 = ...
The solution is given as a step-by-step equation.
