To determine discharge coefficient of given Venturi Meter

Aim: To find out the discharge coefficient of given Venturi meter.

Requirements: Hydraulic bench and Venturi Meter Apparatus.

Principle:

 The working of venturimeter is based on the principle of Bernoulli’s equation.

 Bernoulli’s Statement: It states that in a steady, ideal flow of an incompressible fluid, the total energy at any point of the fluid is constant. The total energy consists of pressure energy, kinetic energy and potential energy or datum energy.

Mathematically

 Here all the energies are taken per unit weight of the fluid.

The Bernoulli’s equation for the fluid passing through the section 1 and 2 are given by

Procedure and Sample Calculation Shown below.

For Calculation You can use Venturi Meter Coefficient Calculator.
