The shape of the sector or quadrant that is submerged into the water ensures that the only pressure exerted by the water on its surface goes to the lower rectangular vertical surface. During the experiment, a counterbalance is placed
A ruler shows the water height from the lower point of the submerged rectangular face on which the phenomenon is studied.
To avoid any friction that deflects the measurement, the entire quadrant system and its lever arm (where we place the counterbalance weights) are supported on bearings with glass spheres, which clearly increase the accuracy of the test.
Measure and check the moment created by the pressure force acting on a submerged vertical flat surface. For this, it is necessary to determine both the magnitude of the force and its center of pressure.
We will distinguish two different cases:
Fully submerged surface.
Partially submerged surface.
Inner diameter 100 mm (D. Int).
External diameter 200 mm (D. Ext).
Width 75 mm.
