PIPE FLOW Meaning and
Definition
-
Pipe flow refers to the transportation or movement of fluid through a closed conduit or pipe. It is a term used in fluid dynamics to describe the behavior and characteristics of fluid flow within a confined channel.
In pipe flow, the fluid can be a gas, such as air, or a liquid, such as water or oil. The flow can be either laminar or turbulent, depending on the velocity and properties of the fluid. Laminar flow occurs when the fluid flows smoothly and in parallel layers with little or no mixing, while turbulent flow is characterized by chaotic and irregular motion with significant mixing.
The behavior of pipe flow is governed by various factors, including the diameter and length of the pipe, the pressure gradient or driving force, and the fluid properties, such as viscosity and density. These factors determine the velocity of the fluid, the pressure distribution along the pipe, and the overall flow rate.
Pipe flow is essential in many engineering applications, including water supply and distribution systems, oil and gas pipelines, and industrial processes involving the transportation of fluids. Understanding and analyzing pipe flow is crucial for designing efficient and reliable systems, as well as for predicting pressure drops, energy losses, and potential flow instabilities.
Overall, pipe flow refers to the movement of fluid within a closed conduit, and its study encompasses the examination of various parameters and phenomena associated with fluid behavior and transport in pipes.
Etymology of PIPE FLOW
The word "pipe" is derived from the Middle English word "pipa", which came from the Old English word of the same spelling. In turn, the Old English term was borrowed from the Latin word "pipa" meaning "tube" or "pipe".
The word "flow" stems from the Old English word "flowan", which means "to flow" or "to stream". This term is related to the Old Norse word "flóð", meaning "flood".
When combined, "pipe flow" refers to the movement or flow of a substance through a pipe or conduit.
