Question

A 300 mmx150mm Venturi meter is used to measure the flow of water, if its Cd=0.97 then Venturi meter constant in SI unit is​

Answer 1

Answer: · A Venturi flow meter is used to measure the the flow velocity of a water main. The water main has a diameter of 30.0 cm, and the constriction has a diameter of 10.0 cm. The two vertical pipes are open at the top, and the difference in water level between them is 3.0 m. Find the velocity, vm (in m/s)of the water in the main.

Explanation:

Answer 2

Venturi meter 300 mm x 150 mm is used to measure water flow, if it’s Cd = 0.97 then Venturi meter does not change in SI unit says:

• Venturi Meter is used in a variety of fields such as, Calculating the flow rate of piped fluid.

• In the industrial sector, it is used to determine the pressure and amount of gas and liquid inside a pipe.

• The flow of chemicals in the pipes.

• Suppose the amount of liquid v1 enters the pipe, as the continuous flow rate of the volume at the inlet (Q1), is equal to the output (Q2), so when the volume of water v1 enters the Venturi meter inlet.

• The same amount of water should be drained out of the outlet, which means it is a second unit v1 / t1 = v2 / t2.
