Turbulent flow occurs when a river flows ____
A
over a smooth river bed
B
through a lake
C
through a meander
D
over an uneven rock surface
Explanation: 

Detailed explanation-1: -Turbulent flow occurs when water moves quickly and runs into many rough obstacles. Using the previous example, turbulent flow will occur is the water is released very quickly from the faucet, and will remain turbulent as the water hits the bottom of the sink and splashes around.

Detailed explanation-2: -Common examples of turbulent flow are blood flow in arteries, oil transport in pipelines, lava flow, atmosphere and ocean currents, the flow through pumps and turbines, and the flow in boat wakes and around aircraft-wing tips.

Detailed explanation-3: -Water undergoes transition to turbulence at low speeds. Most of the water flows we see, such as in streams and rivers, are indeed turbulent.

Detailed explanation-4: -Turbulent flow tends to occur at higher velocities, low viscosity, and at higher characteristic linear dimensions. If the Reynolds number is greater than Re > 3500, the flow is turbulent. Irregularity: The flow is characterized by the irregular movement of particles of the fluid.
