Question

A certain amount of water (H₂O) flows permanently into the pipe venturi(image2) in the figure next to it. In the stretch considered between (1) and (2), it is assumed the losses by friction that were despicable and the uniform properties in the sections are assumed. The entrance area is A₁ while that of throat is A₂ (A₁ > A₂). A pressure gauge whose manometric fluid is Mercury Hg (Y_Hg> Y_H2O) is connected between the input sections and the throat. Show, without omitting any calculation steps that the flow rate at the input (1) is given by(image1):
