Viscosity:Viscosity refers to the measure of a fluid's resistance to flow. It determines how easily or difficultly a fluid can move through pipes or channels.
Bernoulli's Principle: Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. This principle helps explain phenomena like lift in airplanes and the flow of blood in our arteries.
Pascal's Law: Pascal's law states that when there is an increase in pressure at any point in an enclosed fluid system, there will be an equal increase at all other points within the system. This principle is fundamental for understanding hydraulic systems.
