2 cards from this section. Quick, good the night before a test.
What does head loss in fluid dynamics refer to?
Think about the energy we use to pump fluid.
What is the contraction loss coefficient (k_c)?
This value is often assumed to be 0.5 for sudden contractions.
What is the value of the contraction loss coefficient (k_c) for abrupt contractions?
Think about how much turbulence is created in sudden changes.
True or False: Gradual contractions lead to less head loss than sudden contractions.
Consider the effects of fluid flow.
Determine the head loss in a piping system where the inlet diameter is 0.1 meters and the outlet diameter is 0.05 meters. If the flow velocity is 3 m/s, compute the loss using k_c = 0.5.
Refer back to the equations used for calculations.
In a system with varying diameters, analyze and compute head losses for both sudden and gradual transitions, comparing energy lost.
Make sure to detail each step in your analysis and refer to the section for coefficients.
