Fluid Forces

Front

What happens to underwater pressure as depth increases?

Back

Underwater pressure increases as depth increases.

Front

According to Bernoulli's principle, what happens to the pressure exerted by a fluid as its speed increases?

Back

The pressure exerted by the fluid decreases as its speed increases.

Front

What principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished throughout the fluid?

Back

Pascal's Principle.

Front

What does Archimedes' Principle state about the buoyant force on an object submerged in a fluid?

Back

The weight of the water displaced equals the upward force of water on the object.

Front

Why does a steel ship float while a block of the same steel sinks?

Back

The ship's shape allows it to displace a larger volume of water, creating enough buoyant force to float.

Front

What is the formula for calculating pressure in a fluid?

Back

Pressure = Force / Area.

Front

What is the relationship between fluid velocity and pressure in a venturi tube?

Back

As fluid velocity increases in a venturi tube, the pressure decreases.

Front

What is buoyancy?

Back

Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in it.

Front

What is the significance of the center of buoyancy?

Back

The center of buoyancy is the point where the buoyant force acts on a submerged object.

Front

How does temperature affect the density of a fluid?

Back

As temperature increases, the density of a fluid generally decreases.
