Explain the difference between streamline flow and turbulent flow?
Question: Explain the difference between streamline flow and turbulent flow?
Streamline flow, also known as laminar flow, occurs when a fluid flows in parallel layers, with no disruption between the layers. The velocity of the fluid is constant at any point in the fluid and it follows a smooth path. This type of flow is characterized by the Reynolds number (Re) being less than 2000.
On the other hand, turbulent flow is a type of flow in which the fluid undergoes irregular fluctuations or mixing. In contrast to streamline flow, turbulent flow has eddies and vortices that cause the velocity at any point to continuously change in both magnitude and direction. Turbulent flow typically occurs at high velocities and with larger pipes or channels. It is characterized by a Reynolds number greater than 4000.
Between these two types of flows, there is a transitional phase where the flow can switch between laminar and turbulent. This happens when the Reynolds number is between 2000 and 4000.
