Viscosity



Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress (schuifspanning) or tensile stress (trekspanning) . In everyday terms (and for fluids only), viscosity is “thickness” or “internal friction”. Thus, water is “thin”, having a lower viscosity, while honey is “thick”, having a higher viscosity. Put simply, the less viscous the fluid is, the greater its ease of movement (fluidity).
