What is venturimeter?

Venturimeter is a type of flowmeter that works on the principle of Bernoulli's Equation. This device is widely used in the water, chemical, pharmaceutical, and oil & gas industries to measure the flow rates of fluids inside a pipe.

What is the use of Bernoulli's equation?

Bernoulli's principle relates the pressure of a fluid to its elevation and its speed. Bernoulli's equation can be used to approximate these parameters in water, air or any fluid that has very low viscosity.

How to Calculate Actual discharge in venturimeter?

FAQ

What is Actual discharge in venturimeter?
The Actual discharge in venturimeter formula gives the discharge under ideal conditions. The cross-sectional area one and two are at the inlet and throat based on the instrument used for the practical application of Bernoulli's equation and is represented as Q=Cd*((A1*A2)/(sqrt((A1^2)-(A2^2))))*sqrt(2*[g]*H) or actual discharge=coefficient of discharging*((Area of cross section at the inlet*Area of cross section at the Throat)/(sqrt((Area of cross section at the inlet^2)-(Area of cross section at the Throat^2))))*sqrt(2*[g]*head of the liquid). The coefficient of discharging or efflux coefficient is the ratio of the actual discharge to the theoretical discharge, Area of cross section at the inlet, Area of cross section at the Throat and The head of the liquid is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column from the base of its container.
