5 cards from this section. Quick, good the night before a test.
What is the definition of viscosity?
Think about what happens when a fluid moves.
List the three primary dimensions used in fluid mechanics.
Recall the fundamental units of measurement.
What does viscosity measure in a fluid?
Think about fluid movement.
True or False: Kinematic viscosity is the ratio of dynamic viscosity to density.
Recall the relationship between these two types of viscosity.
Calculate the terminal velocity of a sphere of diameter 1 cm and density 1200 kg/m³ falling through a fluid with dynamic viscosity of 0.5 Pa·s. Use Stokes' law.
Remember to consider the density of the fluid in your calculations.
In a viscosity experiment, determine how power relates to viscosity in a system with two rotating plates. Given force and area, derive the relationship.
Use the definitions of shear stress and viscosity in your derivation.
