How is the viscosity of a solid-liquid mixed medium measured? The solid is 20% nickel powder, and the liquid is water; they are mixed together
It depends on whether the mixture can remain in a stable suspended state. If some additives are added, solid nickel powder can be used to remain stably suspended in the mixture; in this case, the measurement of kinematic viscosity can be carried out using the counter-current method. If the mixture cannot remain in a stable suspended state and settles easily, then kinematic viscosity cannot be used; instead, dynamic viscosity measurement methods must be employed, namely the rotary viscometer commonly used.
