Abstract: A kinematic viscosity equation is suggested for capillary viscometers. The equation shows good accuracy in a wide range of viscosity as well as the Reynolds number:
where v is the kinematic viscosity, t is the efflux time, and A,B,C are instrumental constants. The terms of -Bt~(-1) and C are corres ρ onding to the kinetic energy correction and the drainage correction respectively.
In order to simplify the calculation, a linear [η]~[η]~* correlation has been found, where [η] and [η]~* denote the accurate and the approximate (based on ...
