2 cards from this section. Quick, good the night before a test.
What is the formula for Reynolds number?
Think of how viscosity, velocity, and length relate to flow.
State Newton's Law of Viscosity.
Consider how layers of fluid interact.
What is the expression for momentum thickness?
Consider the loss of momentum concept.
True or False: The boundary layer thickness is independent of the Reynolds number.
What happens to boundary layers in laminar vs turbulent flow?
Given a plate with a length of 2 meters submerged in oil moving at a speed of 1 m/s with a viscosity of 0.5 N·s/m², calculate the boundary layer thickness at the end of the plate.
Keep track of parameters to use appropriate formula.
A flat plate experiences airflow with a velocity of 5 m/s and a viscosity of 0.001 Pa·s. If the length of the plate is 0.5 m, find the wall shear stress.
Be sure to use appropriate conversion factors for units.
