Determining the speed of the level of liquid from the lock at a linear variation of the flow from the filling (drainage) pipe

    (Constanta Maritime University)


The lock allows the passage of the ships between the two pools, tail water and upland water, having two different levels. By using the lock chamber, the equalization of these levels is being done. In order to accomplish this, it needs to be filled (drained) with water. Filling or draining the lock chamber with water is usually done gravitationally from or by the two pools. The watergates are fitted with filling (drainage) sistems made up of pipes, gates, in-going-out-going water outlets, etc. The application of our mathematic undertaking will to establish precisely the necessary flow for a certain design requirement- the speed of the level of liquid from the lock chamber, making reference to the most common case – the filling sistem through free fall with the help of some detouring galleries of the gates
