Flow in Pipes

Caractéristiques générales de l’écoulement du tuyau I
Caractéristiques générales de l’écoulement du tuyau I
Pipe flow describes fluid movement through enclosed, fully-filled conduits, typically cylindrical pipes like water pipes or hydraulic hoses, engineered to ...
Caractéristiques générales de Pipe Flow II
Caractéristiques générales de Pipe Flow II
As fluid enters a pipe, it first flows through an entrance region where the velocity profile adjusts, forming a boundary layer along the walls. This ...
Écoulement laminaire
Écoulement laminaire
Laminar flow refers to the smooth, orderly motion of fluid particles in which each particle follows parallel paths with minimal mixing between layers. The ...
Flux laminaire : résolution de problèmes
Flux laminaire : résolution de problèmes
Consider air flowing through the pipe at 300 Kelvin at standard atmospheric pressure, with a mass flowrate of 0.0163 kilograms per second. If the flow is ...
Écoulement turbulent
Écoulement turbulent
Turbulent flow is a fluid movement marked by chaotic shifts in pressure and velocity. Unlike laminar flow, turbulent flow displays complex, irregular ...
Écoulement turbulent : résolution de problèmes
Écoulement turbulent : résolution de problèmes
Consider a liquid that needs to be carbonated. Both the liquid and the carbon dioxide gas are cooled. The temperature is selected as 20 degrees Celsius to ...
Pertes importantes dans les conduites
Pertes importantes dans les conduites
Consider  a fluid flowing through a pipe; it encounters frictional resistance, causing energy losses known as major losses, resulting in a pressure ...
Pertes mineures dans les tuyaux
Pertes mineures dans les tuyaux
Minor losses in pipe systems arise from components like valves, bends, and fittings that disrupt fluid flow, causing energy dissipation through turbulence ...
Systèmes monotubes
Systèmes monotubes
In pipe flow problems, scenarios are grouped by known information and desired calculation and are typically classified as Type I, II, or III. In a Type I ...
Systèmes de tuyauterie multiples
Systèmes de tuyauterie multiples
Multiple pipe systems consist of interconnected pipes that regulate fluid flow across complex networks. They can be arranged in series, parallel, loop, or ...
Mesure du débit des tuyaux
Mesure du débit des tuyaux
Flow measurement devices—such as orifice, nozzle, and Venturimeters—operate by narrowing the flow area. This increases fluid velocity and ...
Mesure du débit des conduites : résolution de problèmes
Mesure du débit des conduites : résolution de problèmes
Consider a spray tank system designed to evenly apply pest-control liquid to plants. The system includes a pressurized tank at 150 kPa filled with ...
