Pascal's Principle Lesson

Front

What is Pascal's Principle?

Back

Pascal's Principle states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid without loss.

Front

What is the formula for pressure?

Back

Pressure (P) = Force (F) / Area (A)

Front

What is the role of incompressibility in hydraulic systems?

Back

Incompressibility ensures that the fluid transmits pressure effectively without changing volume, allowing for efficient force transfer.

Front

What is Archimedes' Principle?

Back

Archimedes' Principle states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced.

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 factors affect fluid pressure?

Back

Fluid pressure is affected by depth of the fluid, density of the fluid, and gravity acting on the fluid.

Front

Why is oil commonly used in hydraulic systems?

Back

Oil is used because it is incompressible, has a low viscosity, and can operate effectively under varying temperatures.

Front

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

Back

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

Front

What is the unit of pressure in the SI system?

Back

The SI unit of pressure is Pascal (Pa), which is equivalent to one Newton per square meter (N/m²).

Front

How does the shape of a container affect fluid pressure?

Back

The shape of a container does not affect the pressure at a given depth; pressure depends only on depth, density, and gravity.
