3 cards from this section. Quick, good the night before a test.
What do the Navier-Stokes equations describe?
Think about fluid motion in various contexts.
What is the continuity equation?
Think about how mass would behave in a flowing fluid.
What do the Navier-Stokes equations account for in fluid mechanics?
Think about the factors impacting how fluids move.
True or False: The velocity potential function is used only in rotational flows.
Consider what types of flow allow for potential functions.
Consider a fluid flowing between two plates, both fixed, under a pressure gradient. If the pressure difference across the length of one meter is known, how would you calculate the flow rate?
Remember to use the velocity distribution relevant to pressure-driven flow.
Derive the shear stress acting on the plate when fluid flows due to a pressure gradient. What parameters do you need to consider?
Focus on the definition of shear stress and how it relates to viscosity.
