3 cards from this section. Quick, good the night before a test.
Define turbulent flow in your own words.
Think about how fluid moves in speeding rivers.
What does the Reynolds number indicate?
Remember the numerical thresholds!
What is the primary characteristic of turbulent flow?
Think about how turbulent river water behaves.
True or False: The Reynolds number can determine whether a flow is laminar.
Recall the ranges for laminar and turbulent flow.
Calculate the change in pressure loss for a rough pipe with a diameter of 0.2 m, flow rate of 0.5 m³/s, and average flow velocity using Darcy-Weisbach equation, given the Darcy friction factor based on Reynolds number is 0.02.
Break down each component of the equation stepwise.
If the diameter of a pipe is reduced to half, explain how this affects the Reynolds number, and the flow's character—discuss implications.
Think about how changes in cross-section affect velocity and continuity.
