Venturi meter

• Venturi meter theory works on the Bernoulli equation such that the velocity increases as the pressure decreases.

• This theory states that when the cross-sectional area of ​​the flow decreases, a pressure difference between the different regions of the flow is created, and it helps to measure the difference under pressure.

• This pressure differential helps to measure the discharge inflow.

Important Points to Remember

· Convergence angle (α)  = 20° to 22°

· Divergence angle (b) = 5° to 7°

· Length of convergent cone (L) = 2.5 D

· Length of divergent cone (L₁) = 7.5 D

· Length of throat (L_th) = D & diameter d = ½ to 1/3

Q.      In order, to avoid separation in venturi meter the angle of divergence is kept

         (a)   10⁰ to 15⁰              (b)   15⁰ to 20⁰

         (c)   5⁰ to 7⁰                 (d)   7⁰ to 10⁰

Ans. c
