n.pl.coefficients of viscosity The degree to which a fluid resists flow under an applied force, measured by the tangential friction force per unit area divided by the velocity gradient under conditions of streamline flow.

Thus, a fluid with a large viscosity has a low fluidity. Two types of viscosity are commonly used: dynamic viscosityμ and kinematic viscosityν. Dynamic viscosity is related to kinematic viscosity by the equation μ = ρν, where ρ is the density of the fluid. The unit of dynamic ...

a viscoelastic model, is a fractional function of time, and relates deformation resistivity and a viscosity coefficient, to output the viscosity coefficient of a sample on the basis of the deformation resistivity values acquired by the resistivity acquisition unit for each of the plurality of times....
has units of length2/time, which is commonly expressed in cm2/s. The diffusion coefficient is a property of a solute in a specific medium or matrix at a constant temperature and pressure. It is dependent on temperature,viscosity, and the size of solute, as described by theEinstein equation...
A high pressure falling cylinder viscosimeter was developed, this unit can be used for determing the pressure-viscosity and pressure-density characteristics of lubricants. The viscous moving seal manner and rheologic flat-spacer sedentary seal structure was adopted in this apparatus. The highest work ...
