Principles of Fluid Mechanics and Related Concepts

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 a decrease in the fluid's potential energy.

Front

What are Pascale's principles?

Back

Pascal's principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and to the walls of its container.

Front

What is pressure in fluids?

Back

Pressure in fluids is the force per unit area exerted by a fluid against a surface.

Front

What is air pressure and the atmosphere?

Back

Air pressure is the force exerted onto a surface by the weight of the air above it, and it decreases with altitude in the atmosphere.

Front

How is pressure transmitted in fluids?

Back

Pressure in a fluid is transmitted equally in all directions throughout the fluid.

Front

What is a hydraulic system?

Back

A hydraulic system is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids.

Front

What are wings and lift?

Back

Wings are designed to create lift, which is the force that opposes the weight of an object and holds it in the air, primarily explained by Bernoulli's principle and Newton's third law.

Front

What is Archimedes' principle?

Back

Archimedes' principle states that the upward buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces.

Front

What is buoyancy force?

Back

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

Front

What is the relationship between density and buoyancy?

Back

Density affects buoyancy; an object will float if it is less dense than the fluid it is placed in, and sink if it is more dense.
