WebDiffusivity has dimensions of length2/ time, or m2/s in SI unitsand cm2/s in CGS units. Temperature dependence of the diffusion coefficient[edit] Solids[edit] The diffusion coefficient in solids at different temperatures is generally found to be well predicted by the Arrhenius equation: WebApr 6, 2024 · Key Takeaways. Kinematic viscosity measures a fluid’s resistance to flow due to internal friction and is expressed in centistokes (cSt). Dynamic viscosity measures a fluid’s resistance to flow due to external forces and is expressed in centipoise (cP). Dynamic viscosity is more commonly used in engineering applications than kinematic viscosity.
