Bernoullis equation is based on the conservation of energy principle applied to flowing fluids, indicating that the total mechanical energy is conserved.
The Reynolds number is a dimensionless quantity that helps predict the flow regime in a fluid, whether it is laminar or turbulent.
A Newtonian fluid has a constant viscosity regardless of the shear rate, meaning the flow does not change its thickness.
The boundary layer is a thin region of fluid near a solid surface where the fluid velocity changes from zero to the free stream velocity.
Water is generally considered an incompressible fluid, meaning its density remains constant under typical conditions.
A hydraulic jump occurs when there is a transition from supercritical (fast) flow to subcritical (slow) flow, causing a sudden rise in the water surface level.
A venturi meter is used to measure the flow rate of a fluid by narrowing the cross-section, causing a pressure difference.
Laminar flow is characterized by a Reynolds number less than 2000, where fluid flows in parallel layers without disruption.
The slip condition describes a scenario in which the fluid shows apparent slipping over a solid surface, often occurring when the no-slip condition fails.
Vortices are formed due to turbulence and flow disturbances, where parts of the fluid rotate, generating swirling flow patterns.
