    Flow in Pipes

    21.1 : General Characteristics of Pipe Flow I01:22

    21.1 : General Characteristics of Pipe Flow I

    Pipe flow describes fluid movement through enclosed, fully-filled conduits, typically cylindrical pipes like water pipes or hydraulic hoses, engineered to ...

    21.2 : General Characteristics of Pipe Flow II01:24

    21.2 : General Characteristics of 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 ...

    21.3 : Laminar Flow01:27

    21.3 : Laminar Flow

    Laminar flow refers to the smooth, orderly motion of fluid particles in which each particle follows parallel paths with minimal mixing between layers. The ...

    21.8 : Minor Losses in Pipes01:25

    21.8 : Minor Losses in Pipes

    Minor losses in pipe systems arise from components like valves, bends, and fittings that disrupt fluid flow, causing energy dissipation through turbulence ...
