2 cards from this section. Quick, good the night before a test.
What is laminar flow?
Think about flow in small, steady streams.
Define turbulent flow.
Consider stormy rivers or rough seas for examples.
What characterizes laminar flow?
Recollect the example of blood flow in arteries.
True or False: Turbulent flow is often found at low velocities.
Think of fast-moving rivers.
A fluid with a diameter of 0.1 m and a kinematic viscosity of 0.00089 m²/s flows with a velocity of 0.2 m/s. Determine whether the flow is laminar or turbulent.
Apply the formula for Reynolds number using given values.
In a pipe of diameter 0.5 m, the average velocity of water is 3 m/s. Calculate the Reynolds number, given that the viscosity of water is 0.001 Pa·s.
Plug in the values into the Reynolds equation.
