3 cards from this section. Quick, good the night before a test.
What defines shear stress?
Think about forces acting on fluid surfaces.
Name one characteristic of turbulent flow.
Consider how fluid moves in different scenarios.
What is the key characteristic of turbulent flow?
Hint: Think of how water behaves in rough conditions.
True or False: The Reynolds number is used to predict flow patterns.
Remember the transition points for flow types.
Calculate the Reynolds number for water flowing through a pipe with a diameter of 0.1 m at a velocity of 3 m/s. Use a kinematic viscosity of 1.004 x 10^-6 m²/s.
Remember to multiply velocity and diameter before dividing by viscosity.
A pipe displays turbulent flow with a turbulent shear stress of 80 Pa and a laminar shear stress of 20 Pa. What is the total shear stress?
Add both shear stresses together.
