What is laminar flow?
Laminar flow is when fluid flows in parallel layers with no disruption between them.
What is viscosity and how is it measured?
Viscosity is a measure of a fluid's resistance to flow. It describes how thick or thin a fluid is. Viscosity is measured using instruments called viscometers
Give an example of a non-Newtonian fluid.
Ketchup.
How does temperature generally affect the viscosity of liquids?
As temperature increases, the viscosity of liquids decreases.
