Stromingsregel

Stromingsregel, literally “flow rule” in Dutch, is not a single canonical law. It is a generic label used in Dutch-language texts for rules that describe how a flow or flux responds to an underlying driving force, such as a gradient of pressure, voltage, or concentration. Because stroming can refer to fluid, electric, or informational flow, the precise form of a stromingsregel depends on the discipline and the model being used.

In fluid mechanics and hydrology, a stromingsregel might take the form of a constitutive equation that links flux to the driving force. Classic examples include Darcy's law for flow through porous media, which relates volumetric flux to hydraulic gradient, and more general linear or nonlinear relationships between forces (such as pressure gradients) and resulting flows (such as velocity or discharge).

In electrical engineering and transport theory, the term is sometimes used conceptually to describe laws that relate a driving potential to a resulting current or flux. Well-known instances are Ohm's law, which links current to voltage, and Fick's law, which links diffusive flux to a concentration gradient.

In traffic flow theory and other social systems, stromingsregel can refer to relationships that connect density, speed, and flow of vehicles or information, illustrating how macroscopic flux emerges from microscopic or individual behavior.

In summary, stromingsregel is best understood as a general concept for a rule that governs how a system's flux responds to driving forces. The exact equation and interpretation are field-specific, so consulting domain-specific sources is recommended for a precise definition.
