This quantity increases as the shear rate increases in dilatant materials.
This quantity increases as the shear rate increases in dilatant materials. In thixotropic materials, this quantity decreases over time when shear stress is constant. The dynamic form of this quantity, written mu or eta, is defined by the equation shear stress equals mu times the velocity gradient. When helium-4 is cooled below the lambda point it acquires a value of zero for this quantity, which is equal to zero for all superfluids. It is constant for a (*) Newtonian fluid and the ratio of inertial forces to those related to this property is called the Reynolds number. For 10 points name this quantity that represents a liquid's resistance to deformation.
