CENTRE OF PRESSURE APPARATUS

PRODUCT DETAILS

Description

The Centre of Pressure Apparatus has been designed todetermine the static thrust exerted by a fluid on asubmerged surface and allow comparison of themeasured magnitude and position of this force withsimpletheory.A fabricated quadrant is mounted on a balance arm,which pivots on knife-edges. The knife-edges coincidewith the centre of arc of the quadrant. Thus, of thehydrostatic forces acting on the quadrant whenimmersed, only the force on the rectangular end facegives rise to a moment about the knife-edges. Thebalance arm incorporates a balance pan for the weightssupplied and an adjustable counterbalancing deadweight. This assembly is mounted on top of an acrylictank, which may be leveled by adjusting screwed feet. Anindicator attached to the side of the tank shows when thebalance arm is horizontal. Water is admitted to the top ofthe tank by a flexible tube and may be drained through adrain cock in the side of the tank. The water level isindicated on a scale on the side of the quadrant.
