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
How does temperature generally affect the viscosity of liquids?
As temperature increases, the viscosity of liquids decreases.
What factors can influence the viscosity of a fluid?
Temperature, pressure, and chemical composition.
What is laminar flow?
Laminar flow is when fluid flows in parallel layers with no disruption between them.
Give an example of a non-Newtonian fluid.
Ketchup.
What is the SI unit of dynamic viscosity?
Pascal-second (Pa·s).
