Properties of Fluids

Front

What is the unit of pressure in the metric system?

Back

Newtons per centimeters squared (N/cm²)

Front

In which direction does buoyant force act?

Back

Upward

Front

How does the density of water compare to air?

Back

Water is about 1,000 times more dense than air.

Front

How do gases exert pressure?

Back

Gases exert pressure evenly in all directions.

Front

What principle states that pressure applied to a fluid is transmitted throughout the fluid?

Back

Pascal's Principle

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 Archimedes' Principle?

Back

Archimedes' Principle states that the upward buoyant force on an object submerged in a fluid is equal to the weight of the fluid that the object displaces.

Front

What is Bernoulli's Principle?

Back

Bernoulli's Principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.

Front

What is the relationship between pressure and depth in a fluid?

Back

Pressure increases with depth in a fluid due to the weight of the fluid above.

Front

What is the formula for calculating pressure?

Back

Pressure = Force / Area
