Define laminar and turbulent flow

WebFor a laminar flow, \(R_{e_{D}} <2300\) and for a turbulent flow, \(R_{e_{D}}>2900\). For a lower end of this range of values, there is a continuous turbulent flow at the farther end from the inlet of the pipe. The flow in the middle of the pipe starts to transition from laminar to turbulent and then back to laminar. WebLaminar flow occurs when fluid runs in a smooth parallel layer without disruption between the layers. At low speed, the fluid will flow without mixing, creating the illusion of the fluid …
