the english translation of kinematic viscosity: kinetic viscosity is the ratio of the dynamic viscosity of a liquid to the density ρ of the fluid at the same temperature. the unit is (m^2)/s. represented by lowercase letter v. note: the unit that has been used is st (s). the relationship between st (s) and (m^2)/s is: 1(m^2)/s=10^4st=10^6cst. (where "cst" is pronounced as "centistoke") the flowing liquid is regarded as many liquid layers moving parallel to each other. each layer has different speeds, forming a velocity gradient (dv/dx), which is the basic characteristic of flow.

formula v = m/p

v = kinematic viscosity [m²s^-1]

m = dynamic viscosity [nsm^-2]

ρ=density[kgm^-3]
