afvloei

Afvloei is a Dutch term meaning the outflow or discharge of fluid from one region, container or system to another. In technical usage it denotes the rate and manner in which liquid leaves a vessel, basin or environment, typically expressed as a flow rate, such as cubic meters per second (m3/s) or liters per second (L/s).

The concept is common in hydrology, hydraulics, and chemical and process engineering, where afvloei describes the outflow from catchments, tanks, reactors or drainage channels. The value depends on factors such as pressure differences, cross sectional area of the outlet, fluid properties and boundary conditions.

In hydrological models, afvloei is used to characterize discharge in rivers and streams or groundwater outflow to surface water bodies. In engineering practice, specifying the afvloei can define outlet design, control strategies, or safety limits.

The term is closely related to but distinct from afvoer, which more generally means an outlet or drainage path, while afvloei emphasizes the dynamic process of flow. Because Dutch technical language varies regionally, speakers may use afvloei, outflow, or discharge interchangeably depending on context.

In summary, afvloei refers to the outflow rate of a liquid from a system, with applications across environmental, civil, and chemical engineering, and is a fundamental parameter in simulations and design.
