CENTRE OF PRESSURE APPARATUS EH25

The EH25 centre of pressure apparatus allows the direct determination of the moment due to the thrust of a liquid onto a totally or partially immersed flat plate: measurements may be compared with data obtained by calculation. The flat plate may be inclined relative to the vertical plane for the study of the general case.

EH25The water is contained in a plexiglass quadrant whose geometrical curved side axes coincide with a measuring beam. The moment is determined by adding or removing weights to the arm. The head of water is read directly on the transparent scale to within 2 mm.

Teaching objectives

- Measurements of the centre of pressure of a vertical plane surface at different depths.
- Study of the general case of a plane surface inclined at different angles, and at different depths.
