Orifice, Venturi, and Pitot Tubes Quiz

What is the primary purpose of using an orifice in fluid mechanics?

• To reduce the pressure of the fluid

• To measure the flow rate of the fluid

• To increase the velocity of the fluid

• To maintain constant pressure in a pipe

In a Venturi meter, where is the pressure lowest?

• At the inlet

• At the throat

• At the outlet

• It remains constant throughout

Which principle does the Venturi effect rely on?

• Newton's Second Law

• Bernoulli's Principle

• Pascal's Law

• Boyle's Law

The Pitot tube is primarily used to measure:

• Fluid density

• Pressure drop

• Flow velocity

• Viscosity

What is the main difference between an orifice meter and a Venturi meter?

• Venturi meter provides more accurate measurements

• Orifice meter is more expensive

• Venturi meter causes a higher energy loss

• Orifice meter has a larger pressure drop

The Pitot tube can measure both static and dynamic pressures.

• True

• False

A Venturi meter is less efficient compared to an orifice meter because it causes more energy loss.

• True

• False

In a fluid flow through an orifice, the velocity of the fluid decreases as it passes through the orifice.

• True

• False

The ___________ tube is commonly used to measure the velocity of airflow in aerodynamics.

The point where the cross-sectional area is the smallest in a Venturi meter is called the ___________.
