Bernoulli's Equation
Describes the conservation of energy in a flowing fluid, represented as
Navier-Stokes Equations
A set of nonlinear partial differential equations that describe the motion of fluid substances, represented as
Reynolds Number
Dimensionless quantity used to predict flow patterns in different fluid flow situations, represented as
Continuity Equation
Expresses the conservation of mass in fluid dynamics, often simplified for incompressible flow as
Laminar Flow
Type of fluid motion in which all the particles in the fluid move along smooth, regular paths in layers or lamina, with minimal mixing and disruption between the layers.
Turbulent Flow
Type of fluid motion characterized by chaotic changes in pressure and flow velocity. It is associated with high momentum convection and eddy formation.
Boundary Layer
The layer of fluid in the immediate vicinity of a bounding surface where effects of viscosity are significant, generating a velocity gradient perpendicular to the flow direction.
Darcy-Weisbach Equation
An empirical equation that describes the pressure losses due to friction along a given length of pipe with a constant diameter, represented as
Mach Number
A dimensionless quantity representing the ratio of the speed of an object moving through a fluid to the speed of sound in that fluid, defined as
Stream Function
A mathematical function used to simplify the description of a two-dimensional, incompressible flow, where the function's value remains constant along streamlines and its partial derivatives are related to the velocity components.
