Fluid Mechanics Flashcard

Front

What is atmospheric pressure?

Back

The weight of air above a point.

Front

Why are the effects of drag significant in vehicle design?

Back

They are crucial for improving speed and efficiency.

Front

What is density?

Back

Density is defined as Mass / Volume.

Front

Why is understanding fluid dynamics essential?

Back

It is crucial for engineering and safety in construction and aviation.

Front

In which scenarios can Bernoulli’s principle be observed?

Back

In the behavior of a soccer ball in motion.

Front

What is the formula for calculating pressure?

Back

Pressure = Force / Area.

Front

What is buoyancy?

Back

Buoyancy is the upward force exerted by a fluid on an object immersed in it.

Front

What is the principle of continuity in fluid mechanics?

Back

The principle states that the mass flow rate must remain constant from one cross-section of a pipe to another.

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow.

Front

What is the difference between laminar and turbulent flow?

Back

Laminar flow is smooth and orderly, while turbulent flow is chaotic and irregular.
