Review for forces in Fluids

Front

What is the principle that states the weight of a fluid displaced by an object is equal to the buoyant force acting on the object?

Back

Archimedes Principle

Front

What is the term for the force exerted by a fluid on an object immersed in it?

Back

Buoyant Force

Front

What does Bernoulli's principle state about the relationship between the speed of a fluid and its pressure?

Back

As the speed of a fluid increases, its pressure decreases.

Front

According to Pascal’s principle, what happens to pressure in a hydraulic system when a force is applied to a piston?

Back

The pressure is transmitted equally throughout the fluid.

Front

What is the formula for calculating pressure in a fluid?

Back

Pressure = Force / Area

Front

What is the relationship between the area of a piston and the force exerted in a hydraulic system according to Pascal's principle?

Back

If the area of the second piston is larger, the force exerted is greater, but the pressure remains the same.

Front

What is the definition of fluid dynamics?

Back

Fluid dynamics is the study of the behavior of fluids in motion.

Front

What is the difference between laminar flow and turbulent flow in fluids?

Back

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

Front

What is the significance of the continuity equation in fluid mechanics?

Back

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

Front

What is the term for the resistance of a fluid to flow?

Back

Viscosity
