The Reynolds number, Re = VD/υ, can be used to measure the laminarity of flow. The smaller the Reynolds number, the more laminar the flow. Therefore, to achieve better laminar flow, V and D (velocity of fluid and diameter of pipe) should be small and υ, the kinematic viscosity of the fluid, should be large. Therefore, since pipe diameter and viscosity is fixed in this circumstance, the slower the velocity of the flow, the more laminar the flow. Open the faucet to a small degree and the flow will be laminar. Turn the facet open fully will (for some faucets) cause turbulent flow depending on the maximum velocity of water allowed by the faucet.
Smoke rising from a flame. At first the smoke rises with laminar flow before becoming turbulent just a few centimetres above the source.
Coz poiseuille eq is for poiseuille flow, which is a laminar flow, not turbulent flow. And it also need to be a fully developed , pressure driven flow.
This question is its own answer. The flow patterns in laminar flow are laminar.
Laminar flow can be defined by the help of Reynold's number that can be determined by conducting experiments. A Reynold number <=2000 indicates that the flow is laminar.
The equation assumes steady state or laminar flow and hence cannot be used for turbulent flows.
Increasing the velocity of the fluid will cause a laminar flow to become turbulent.

Laminar flow refers to smooth, orderly flow with predictable patterns, while turbulent flow is characterized by chaotic, irregular movement with swirling vortices and mixing. The transition from laminar to turbulent flow occurs when the flow speed or viscosity of the fluid increases, leading to the breakdown of laminar layers and the onset of turbulence.

Flow in a Venturi tube can be either laminar or turbulent, depending on the flow rate and Reynolds number. At low flow rates, the flow tends to be laminar, while at high flow rates, it can transition to turbulent flow.
Turbulent flow transports more sediment than laminar flow due to the increased velocity and mixing of particles in turbulent flow. This helps to keep sediments suspended and advected downstream more effectively.
Laminar flow is smooth and orderly, with fluid moving in parallel layers, while turbulent flow is chaotic and unpredictable, with swirling and mixing of fluid. Laminar flow has low energy loss and is easy to predict, while turbulent flow has high energy loss and is harder to predict.
In fluid dynamics, laminar boundary layers have smooth and orderly flow, while turbulent boundary layers have chaotic and irregular flow. Laminar flow is characterized by layers of fluid moving in parallel, while turbulent flow involves swirling and mixing of fluid layers. Turbulent boundary layers have higher levels of energy and mixing compared to laminar boundary layers.
The laminar flow hood depends on the laminar air flow to sweep away pathogens from the hood. If there is obstruction, the laminar air flow pattern will be disrupted. The laminar air flow will then change to turbulent air flow.
In fluid dynamics, turbulent flow is chaotic and unpredictable, with swirling eddies and fluctuations in velocity and pressure. Laminar flow, on the other hand, is smooth and orderly, with layers of fluid moving in parallel without mixing. Turbulent flow has higher energy losses and mixing, while laminar flow has lower energy losses and is easier to predict and control.

You want laminar around a bicycle for less resistance, but turbulent in rafting so that you get all of the white water
