Water level deflection

from Wikipedia, the free encyclopedia

The water level deflection is defined as a signed deviation from an imaginary or fixed water level at rest . Since the latter is due to the exclusive effect of the acceleration due to gravity , at least one further acceleration of the water particles is required for any water level deflection to occur .

For example, when the water (or another liquid) rotates in a cylindrical container, centrifugal acceleration causes a water level deflection in the form of a paraboloid of revolution , the extreme positive and negative deviations of which from the water level at rest are equal .

In contrast, a sequence of moving alternately positive and negative water level deflections of different amounts represents the generic term for the types of water waves for whose formation, in addition to the acceleration due to gravity , the centrifugal acceleration is also essential. Waves with only positive water level deflection are referred to as single wave , surge wave or bore . In contrast, the sunk wave shows only negative water level deflection.

In hydraulic elevators with promotion on an inclined plane , the amount that must tangential to be limited in order to avoid harmful ship movements due to excessive water level steering the ship trough.
