3 cards from this section. Quick, good the night before a test.
Define head loss in the context of fluid flow.
Think about the energy lost as fluid moves through a pipe.
What is the Darcy friction factor for laminar flow?
Recall the relationship between Reynolds number and friction.
What is the formula for head loss in laminar flow?
Recall how each component influences energy loss.
True or False: The Darcy friction factor is constant for laminar flow.
Think about how friction factor is derived from flow conditions.
Given a pipe with a diameter of 0.15m, length of 20m, and wall shear stress of 100 N/m², calculate the head loss in the system. Assume the fluid density is 1000 kg/m³.
Make sure to correctly calculate the units as you substitute.
Discuss how reducing the pipe diameter affects the head loss for a fluid flowing at a constant pressure gradient.
Think about how energy distribution and friction take place with changing diameters.
