2 cards from this section. Quick, good the night before a test.
Define momentum.
Think about what affects the quantity of motion an object has.
What is the beta factor in laminar flow?
This factor corrects for differences between average and actual momentum flux.
What is the beta factor for laminar flow?
Consider the role of laminar flow in flow dynamics.
True or False? Turbulent flow has a beta factor closer to 1.
Think about how turbulence affects flow behavior.
Calculate the force exerted by a turbulent jet impacting a flat plate. Given a diameter of 25 mm, velocity of 10 m/s, and density of 1000 kg/m3.
Start by calculating the area from the diameter.
Describe the impact of shear stress on momentum conservation at the boundary of a turbulent flow.
Consider how viscosity and fluid layers interact.
