Flow in Pipes

الخصائص العامة لتدفق الأنابيب I
الخصائص العامة لتدفق الأنابيب I
Pipe flow describes fluid movement through enclosed, fully-filled conduits, typically cylindrical pipes like water pipes or hydraulic hoses, engineered to ...
الخصائص العامة لتدفق الأنابيب II
الخصائص العامة لتدفق الأنابيب 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 ...
التدفق الصفحي
التدفق الصفحي
Laminar flow refers to the smooth, orderly motion of fluid particles in which each particle follows parallel paths with minimal mixing between layers. The ...
التدفق الرقائقي: حل المشكلات
التدفق الرقائقي: حل المشكلات
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 ...
التدفق المضطرب
التدفق المضطرب
Turbulent flow is a fluid movement marked by chaotic shifts in pressure and velocity. Unlike laminar flow, turbulent flow displays complex, irregular ...
التدفق المضطرب: حل المشكلات
التدفق المضطرب: حل المشكلات
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 ...
خسائر كبيرة في الأنابيب
خسائر كبيرة في الأنابيب
Consider  a fluid flowing through a pipe; it encounters frictional resistance, causing energy losses known as major losses, resulting in a pressure ...
خسائر طفيفة في الأنابيب
خسائر طفيفة في الأنابيب
Minor losses in pipe systems arise from components like valves, bends, and fittings that disrupt fluid flow, causing energy dissipation through turbulence ...
أنظمة الأنابيب المفردة
أنظمة الأنابيب المفردة
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 ...
أنظمة الأنابيب المتعددة
أنظمة الأنابيب المتعددة
Multiple pipe systems consist of interconnected pipes that regulate fluid flow across complex networks. They can be arranged in series, parallel, loop, or ...
قياس معدل تدفق الأنابيب
قياس معدل تدفق الأنابيب
Flow measurement devices—such as orifice, nozzle, and Venturimeters—operate by narrowing the flow area. This increases fluid velocity and ...
قياس معدل تدفق الأنابيب: حل المشكلات
قياس معدل تدفق الأنابيب: حل المشكلات
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 ...
