The behavior of jets of water and dilute polymer solutions issuing from curved pipes has been experimentally investigated. A jet column from a curved pipe is not disintegrated up to a larger Reynolds number as compared with a jet column from a straight pipe. It has been found that a particular region on the jet length exists between the laminar region and the transition one in the flow of solutions. The transition Reynolds number to this region has been formulated in terms of the Weber number, Weissenberg number and the ratio of curvature radius. Empirical formulas for jet length also have proposed in the laminar, the turbulent and the particular regions. Furthermore, it has been shown that there is a correlation between jet breakup length and disturbance in the flow.
