3 cards from this section. Quick, good the night before a test.
What is the shape of a laminar flow profile?
Think about how the velocity distributes across the section.
Define 'velocity defect'.
Related to the terms discussed, especially in turbulent scenarios.
What is the velocity profile of laminar flow?
It's named after a famous fluid dynamic principle.
True or False: Turbulent flow has a linear velocity profile.
Think of the characteristic shapes we discussed.
Given a turbulent flow in a pipe, calculate the shear stress if the velocity defect at a specific radius is 2 m/s and the fluid density is 800 kg/m³.
Focus on deriving u* first using the velocity defect.
If the height of surface irregularities is 0.1 mm and the viscous sublayer thickness is measured at 0.4 mm, classify the boundary as smooth, rough, or transitional.
Refer to the classification criteria discussed in class.
