3 cards from this section. Quick, good the night before a test.
What is the Reynolds number used for?
Think about fluid behavior.
At what Reynolds number does turbulent flow generally occur?
Remember the threshold from our discussion.
What defines a turbulent flow?
Consider definitions we discussed in class.
Is a Reynolds number below 2300 indicative of turbulent flow?
Recall the thresholds we covered.
A fluid with density 1200 kg/m³ and viscosity 0.002 Pa·s flows through a pipe of 0.1 m diameter at a speed of 3 m/s. Determine if the flow is laminar, transitional, or turbulent.
Make sure you use the correct formula and factor in all parameters.
What would happen to the Reynolds number if the pipe diameter were halved while keeping all other factors constant? Discuss the impact on flow type.
Think through how changing each parameter affects the classification.
