2 cards from this section. Quick, good the night before a test.
What characterizes laminar flow?
Think about how fluid moves in a straight line.
What is the maximum Reynolds number for laminar flow?
It's a key number you need to remember.
What type of flow has a Reynolds number below 2300?
Consider characteristics of slow, smooth flow.
True or False: Turbulent flow is characterized by smooth streamlines.
Think about flow behavior in chaotic situations.
A liquid with a density of 800 kg/m³ flows in a pipe of diameter 0.1 m at a speed of 2 m/s with a dynamic viscosity of 0.002 Pa·s. Determine the flow type.
Remember, Re > 4000 indicates turbulent flow.
Design a pipeline system that ensures laminar flow for a fluid with a density of 900 kg/m³ and viscosity of 0.003 Pa·s. What should the maximum velocity be?
Consider how to keep the Re below 2300 while factoring in fluid properties.
