Experimental Determination of Hydrodynamic Resistance Coefficients and the Lifting Force of Various Pipeline Crossing Methods

This article presents the results of an experimental research on the water flow implication of pipeline crossing models. The coefficients of the hydrodynamic resistance and lifting force were determined for pipelines laid along the bottom at different angles to the oncoming flow, embedded in the bottom of a watercourse at different depths, and protected by flexible concrete pavement. Furthermore, the test results of research on the turbulent flow force impact on various types of pipeline crossings were analyzed.
