Question

describe what is a stream line flow and a turblent flow

Answer 1

When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Laminar flow tends to occur at lower velocities, below a threshold at which it becomes turbulent.

Answer 2

when a fluid is flowing through a closed channel between two flat plates.A stream is a flow of a fluid in which velocity at any point is constant or varies in a regular manner. turblent flow in which the fluid undergoes irrregular fluctuations or mixing.
