What is the formula for discharge through Venturi meter?

What is the formula for discharge through Venturi meter?

As pipe is horizontal Z1= Z2, Where [h= (p1-p2)/ρg], difference of pressure heads at sections 1 and 2. From the continuity equation at sections 1 and 2, we get, This expression is the Theoretical Discharge of Venturi Meter.

What is flow through a Venturi meter?

Venturi meters are flow measurement instruments which use a converging section of pipe to give an increase in the flow velocity and a corresponding pressure drop from which the flowrate can be deduced. They have been in common use for many years, especially in the water supply industry.

How do you calculate actual flow rate?

Q=Vt Q = V t , where V is the volume and t is the elapsed time. The SI unit for flow rate is m3/s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min).

How is Venturi Reynolds number calculated?

The Reynolds number (Re) of a flowing fluid is calculated by multiplying the fluid velocity by the internal pipe diameter (to obtain the inertia force of the fluid) and then dividing the result by the kinematic viscosity (viscous force per unit length).

At what principle Venturi meter based determine the rate of flow liquid through Venturi meter?

Bernoulli’s equation
EXPLANATION: The Venturi-meter is a device to measure the flow speed of the incompressible fluid. Venturimeter works on the principle of Bernoulli’s equation. Hence, option 3 is correct.

How do you calculate volume flow through mass flow rate?

Q = v * A, Where v is the velocity of the fluid and A is the cross-section area the fluid is passing through. If the mass flow rate was given, the volume flow rate can be sought by dividing the mass flow rate by density.

How to use venturi meter for measuring flow rate?

CONSTRUCTION: Venturi meter is very simple in construction.

• WORKING: Working of venturimeter is so simple.
• APPLICATIONS: As discussed above venturimeter is used to measure the discharge in flow through pipes.
• ADVANTAGES: The main advantage of venturimeter is it has very less losses and high accuracy.
• What is Venturi flow meter and how it works?

What is a Venturi Meter? Venturi Meter is a device in which pressure energy is converted into kinetic energy and it is used for measuring the rate of flow of liquid through pipes. It is invented by American Engineer Clemans Herchel and named by the Italian physicist Giovanni Venturi. It works on the basic principle of Bernoulli’s Equation.

What is the difference between Venturi and Orifice meters?

Venturi meter presents a costlier method to measure the rate flow of fluid through the pipe.

• Energy losses are less in a venturi meter whereas Energy losses are more in case of an orifice meter.
• Venturi meter has a high coefficient of discharge as compared to an orificemeter.
• Venturi meter is more complex to fabricate than an orifice meter.
• What is the working principle of Venturi meter?

Venturi meters are used to measures the flow rate of a fluid through a pipe.

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