Abstract
The invention relates to a fluid transport pipe. A first unit channel in which a channel cross-sectional area continuously decreases toward a downstream side and a second unit channel in which a channel cross-sectional area continuously increases toward the downstream side are alternately combined. A ratio A (=L/{[Smax]-[Smin]}) is set within a range in which a drag reduction rate Rbecomes a positive value. The fluid transport pipe includes: a first opening formed in a channel wall of the first unit channel; a second opening formed in a channel wall of the second unit channel; and a bypass channel that allows by-passing of a flow from the first unit channel to the second unit channel through the openings.
