Viscosity is a quantity expressing the magnitude of internal friction, as measured by the force per unit area resisting a flow in which parallel layers unit distance apart have unit speed relative to one another.
Viscosity is how “thick” a fluid is.
Centipoise, Centistokes, Krebs Units, SSU’s, are some measurements of viscosity. At Dynamix we prefer if you tell us the Centipoise, CP’s please!
