3 cards from this section. Quick, good the night before a test.
What is a stress tensor?
Think of it as a way to quantify how force is distributed within an object.
How many components does a stress tensor have?
Remember that it includes both normal and shear stresses.
What does a momentum flux correction factor account for?
Think about how fluids behave under real conditions.
True or False: Shear stress acts perpendicular to the surface.
Recall the characteristics of different stress types.
Consider a cylindrical pipe with a radius of 0.1m experiencing laminar flow at 0.2 m/s. Calculate the momentum flux correction factor assuming parabolic velocity distribution.
Think about integrating velocity moments to correctly account for the non-uniform distribution.
A jet of water strikes a flat surface at an angle. Derive an expression for momentum force considering both the incoming and outgoing velocities.
Consider how both horizontal and vertical components impact net forces in this scenario.
