<p>PROBLEM TO BE SOLVED: To solve a problem with a method for transporting fluid using a pipe conduit which has a complicated structure for reducing friction resistance thereof by lessening a turbulent fluid flow in a manner that provides the fluid with pulsation generated by accelerating a fluid flow with a blade-shaped rotor installed in the pipe conduit to transport the fluid.SOLUTION: A fluid transport pipeline is configured to serially connect a plurality of flow passages to increase an average cross-sectional flow rate of fluid and a plurality of flow passages to decrease the same. The flow passages to increase the cross-sectional flow rate of the fluid may include a narrowing flow passage with a cross-sectional area thereof perpendicular to a longitudinal direction of the flow passage gradually narrowed along the longitudinal direction. The flow passages to decrease the cross-sectional flow rate of the fluid may include an expanding flow passage with the cross-sectional area thereof gradually expanded along the longitudinal direction.</p> |
