5 cards from this section. Quick, good the night before a test.
What is viscosity?
Think about how thick a material feels when you try to pour it.
Define shear stress.
Consider forces that cause layers in a fluid to slide over one another.
What happens to the viscosity of a liquid as temperature increases?
Think about how hot syrup is easier to pour.
True or False: Newtonian fluids have a variable viscosity based on the shear rate.
Remember fixed behavior in common fluids.
Calculate the viscosity of a gas if a = 1.3, b = 0.5, and T = 300K using the Sutherland equation.
Follow the Sutherland equation closely and perform each step of the calculation.
Compare the viscosity changes of water when heated from 20°C to 100°C and discuss potential industrial implications.
Consider flow rates and pressure when water is less viscous.
