Question

4. Since we didn’t manage to complete this in class, I would like you to derive an expression linked to the Venturi tube. Derive an expression for the speed at the meter entrance (V) in terms of the areas A and a, and the density of the fluid in the pipe ρ, the height of the fluid in the manometer h and the densities of the fluid in the pipe ρ and the manometer ρf. Please use your own words rather than copying direct from a textbook.
