nature : When the shear stress in the material, the material flow resistance (permanent deformation) in nature. Consistency is the internal friction material of a performance, liquid, semi-mobile body, semi-solid and solid, and the shear stress resistance movement (deformation), with its stress deformation disproportionate. Consistency general description of the movement of an object, it is a material difference between a gas, different viscosity of the liquid or solid rigid. Comprehensive quantitative reflects a consistency of objects it needs to know in force under the full flow, it is often very complex. The non-Newtonian fluid sometimes used shear stress (τ) - shear rate (r) curve on a shear rate of the slope value said objects to the consistency. The general consistency of liquid consistency Cup in France, that is 25 ° C, 30 ~ 100s, consistency cup liquid from the export volume of the outflow 50ml time namely the liquid consistency.
