In a horizontal Venturi meter, the throat (narrow section) has area A t = A/2 where A is pipe area. Fluid density ρ, velocity at pipe entrance v. The height difference Δh in the manometer (density ρ_m) is:

Question

Accepted Answer

Δh = 3ρv²/(2(ρ_m - ρ)g)

Answer

Δh = ρv²/2ρ_m g overall

Answer

Δh = v²/2g in most cases

Answer

Δh = 4ρv²/ρ_m g under typical conditions
