5 cards from this section. Quick, good the night before a test.
What is the definition of head loss?
Think about energy loss in pipes.
Define turbulent flow.
Consider how water behaves in a fast-moving river.
What is the purpose of the energy loss coefficient (K)?
Consider what happens at junctions in a pipe.
Is head loss only caused by friction?
Think about how valves affect flow.
Calculate head loss due to friction in a pipe with a known length, diameter, roughness and flow rate using the Darcy-Weisbach equation.
Ensure you have the correct friction factor for the flow type.
Derive the modified Bernoulli’s equation including head loss terms for a system with a valve.
Identify all terms on each side carefully.
