3 cards from this section. Quick, good the night before a test.
Define viscosity and explain its significance in fluid flow.
Think about how different liquids behave when poured.
What is the no-slip condition?
Consider what happens to a fluid at a boundary.
What is Reynolds number primarily used for?
Think about its relation to fluid motion.
True or False: In laminar flow, fluid particles move in parallel layers with no mixing.
Revisit the concept of flow patterns.
Consider a system where oil of viscosity 0.5 Pas flows through a circular pipe of diameter 0.2 m. If the pressure difference measured across 10 m is 500 Pa, calculate the average velocity.
Break down the formula and substitute the known values.
A fluid flows between two parallel plates. The distance between plates is 0.05 m, and the viscosity is 0.1 Pas. If the maximum speed is measured at 2 m/s, find the discharge per unit width.
Focus on how to rearrange the equation for discharge.
