SILICONE FLUIDS - Gelest, Inc.
www.gelest.comKinematic Viscosity Differs from viscosity in that it is the measure of volume flow of a liquid, defined as a stoke (St.) A stoke equals 1 cm.2/sec. or 10-4m2/sec. A centistoke, cSt. = .01 St. = 1 mm.2/sec. Kinematic viscosity of a liquid (stokes) can be converted to viscosity (poise) by multiplying by the density of the fluid.

Viscosity and drag - Brock University
www.physics.brocku.caViscosity and drag Drag force arises when an object moves through a fluid or, equivalently, when fluid flows past an object. In general, the drag force grows larger with increased flow velocity, but viscosity is a complex phenomenon that cannot be reduced to the simple relationship “drag force is proportional to velocity”.
Viscosity Converting Chart - netzschusa.com
www.netzschusa.comA converting table between viscosity units like : Centiposes, milliPascal, CentiStokes and SSU: The viscosity of a fluid is its resistance to shear or flow, and is a measure of the fluids adhesive/cohesive or frictional : properties. This arises because of the internal molecular friction within the fluid producing the frictional drag effect.
