Jul 31, 2004 #2 jmw Industrial Jun 27, 2001 7,435 All you have to remember is which one to divide by density to get the other. Best you check, as i always have to do, with a quick internet search.

Aug 1, 2004 #3 sean01 Automotive Aug 14, 2003 48 hi bicolexpress, Kinematic Viscosity is the term normally given to a coefficient which describes the diffusion of momentum. The formula for it is normally given as v=n/rho where n is the dynamic viscosity and rho the density of the material under consideration. The units for kinematic viscosity are the Stoke The dynamic viscosity of a material is usually defined from the term |shear stress|=n|strain rate| For a newtonian fluid it is calculated from the following formula Stress = n du/dy The relationship between shear stress and strain rate is also known as the materials rheology The units of dynamic viscosity are the poise Hope this helps Sean Upvote 0 Downvote
