3 cards from this section. Quick, good the night before a test.
What is the formula to calculate the Reynolds number?
Think about what each symbol represents in terms of fluid properties.
Define laminar flow.
Consider how the fluid layers behave.
What does the Reynolds number measure?
Think about how engineers differentiate between smooth and chaotic flows.
True or False: A lower Reynolds number indicates turbulent flow.
Recall the values indicating laminar versus turbulent conditions.
A fluid has a density of 1000 kg/m³ and an average velocity of 5 m/s. If the length is 0.1 m and the viscosity is 0.001 Pa.s, calculate the Reynolds number.
Use the formula carefully while substituting the values.
Discuss how variations in temperature could affect the viscosity and thus the Reynolds number of a fluid.
Consider the physical properties of fluids as they react to temperature changes.
