Singularity behavior of flow in a curved pipe is analyzed. A series related to a similarity parameter is obtained by using algebraic programming language MAPLE. The series is then analyzed by various generalizations of the approximate methods. The result is not conclusive, but we show approximately the dominating behavior of the flow near the (unphysical) singularity point.
