Question 1 of 4
What primary mechanical behavior distinguishes a fluid from a solid?
Explanation: Fluids continuously deform when subjected to shear stress, unlike elastic solids that reach static equilibrium.
Question 2 of 4
What does the Reynolds number quantify?
Explanation: The Reynolds number is a dimensionless metric comparing inertial forces against viscous forces to predict flow regimes.
Question 3 of 4
What happens to static pressure along a streamline when fluid velocity increases according to Bernoulli?
Explanation: Bernoulli's principle dictates that an increase in fluid speed occurs simultaneously with a decrease in static pressure.
Question 4 of 4
How does fluid dynamics change at microscopic scales (low Reynolds number)?
Explanation: At low Reynolds numbers, viscous forces dominate completely, eliminating inertial effects and making reciprocal motion non-propulsive.
