What is Viscosity, and Why is Measuring Viscosity Important?

Viscosity is the measure of a substance's resistance to motion under an applied force. The formula for measuring viscosity is fairly simple: viscosity = shear stress / shear rate. The result is typically expressed in centipoise (cP), which is the equivalent of 1 mPa s (millipascal second). Shear stress is the force per unit area required to
