Abstract

In precise measurement of viscosity of low viscous fluid with capillary method, it is necessary to consider the kinetic energy correction. The coefficient of the kinetic energy correction has been usually treated as constant value for a certain capillary tube. Recently, it has been observed that the coefficient of the kinetic energy correction is not strictly constant and varies with Reynolds number.
