The break‐up of a stationary viscous liquid cylinder surrounded by an immiscible viscous liquid contained in a circular tube by capillary forces at the fluid interface is considered. It was found that the maximum growth‐rate parameter f * depends upon η'/η , the ratio of the viscosity of the inner liquid to that of the outer liquid and a/S, the ratio of the radius of the inner liquid cylinder to that of the tube. Both f * and corresponding wavelength parameter (2πa/λ)* have been calculated theoretically; measured values of both parameters are in good agreement with the theory.
