Important concepts to remember
The pressure exerted by a fluid at rest, which increases with the depth of the fluid.
A principle stating that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.
The upward force exerted by a fluid that opposes the weight of an object submerged in it.
An equation that describes the behavior of a moving fluid, relating pressure, velocity, and elevation.
A dimensionless number used to predict the flow type of a fluid, indicating whether it is laminar or turbulent.
A smooth, orderly fluid flow in which layers of fluid slide past each other with minimal mixing.
A chaotic fluid flow characterized by irregular fluctuations and mixing.
A principle that states the mass flow rate of a fluid must remain constant in a closed system, provided the flow is steady and incompressible.
A measure of a fluid's resistance to flow, with high viscosity indicating thick fluid and low viscosity indicating thin fluid.
A set of equations that describe the motion of viscous fluid substances, accounting for forces like pressure and viscosity.
The thin layer of fluid near a surface where the velocity changes from zero at the surface to the free-stream velocity.
The volume of fluid passing through a cross-sectional area of a pipe per unit of time.
The formation and collapse of vapor bubbles in a fluid, often due to low pressure, leading to shockwaves that can damage equipment.
A method used to reduce complex physical problems into their fundamental dimensions, simplifying calculations and experiments.
A principle stating that any object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object.
