3 cards from this section. Quick, good the night before a test.
What is the formula to calculate discharge?
Think of how we measure flow over time.
What does Reynolds number indicate?
Remember the critical value for flow categorization.
What is the hydraulic diameter of a circular pipe?
Think of how diameter is defined.
True or False? Laminar flow occurs at high Reynolds numbers.
Remember the critical value for classifying flow.
If the pipe's diameter is halved, calculate the new discharge rate if the original was 4.17 x 10^-3 m³/s.
Think about how area changes with diameter.
Derive a formula for pressure drop in a long pipe if fluid characteristics (viscosity and density) and flow velocity are altered.
Recall what aspects lead to a change in flow characteristics.
