• Converging section, throat, and diverging section

• Inlet, outlet, and middle section

• Straight section, curved section, and spiral section

Explain the working principle of a venturimeter.

• The venturimeter works based on the principle of Boyle's law.

• The venturimeter works based on the principle of Newton's third law.

• The venturimeter works based on the principle of Ohm's law.

• The venturimeter works based on the principle of Bernoulli's equation.

What are the advantages of using a venturimeter in fluid flow measurement?

• It provides inaccurate and unreliable flow rate measurements

• It is expensive

• It provides accurate and reliable flow rate measurements, has low pressure drop, and is cost-effective.

• It has high pressure drop

Discuss the disadvantages of using a venturimeter.

• No pressure drop

• High accuracy at low flow rates

• No susceptibility to blockages

• Potential disadvantages include pressure drop, susceptibility to blockages, and limited accuracy at low flow rates.

In which applications is a venturimeter commonly used?

• Plastic

How does a venturimeter measure the flow rate of a fluid?

• By using the principle of Bernoulli's equation

• By analyzing the color of the fluid

• By measuring the temperature of the fluid

• By counting the number of bubbles in the fluid

What is the purpose of the throat section in a venturimeter?

• To create a constriction in the flow and cause pressure decrease and velocity increase

• To increase pressure and decrease velocity

• To measure the flow rate

• To have no effect on the flow

Explain the concept of pressure difference in a venturimeter.

• The pressure difference in a venturimeter is created by the change in velocity of the fluid as it passes through the constriction.

• The pressure difference in a venturimeter is caused by the shape of the pipe

• The pressure difference in a venturimeter is due to the color of the fluid

• The pressure difference in a venturimeter is caused by the temperature of the fluid

What are the factors that can affect the accuracy of a venturimeter in flow measurement?

• Temperature of the surrounding area

• Flow disturbances, improper installation, and blockages in the venturi tube

• Material of the venturi tube

• Color of the venturimeter
