Center of Pressure
Product Code : LSK-FM-10460
Center of Pressure apparatus (SKU LSK-FM-10460) measures the moment due to hydrostatic thrust on a fully or partially submerged plane surface, set either vertical or inclined, so students can compare measured values with theory. It suits hydrostatics practicals in civil and mechanical engineering courses. Science Lab Supplies manufactures the quadrant apparatus at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and colleges, polytechnics, contractors and distributors receive their quotation from that same address.
Specifications
The centre of pressure quadrant and its fittings are covered row by row in the table. In short, a vertical panel holds a clear plastic quadrant whose curved sides are centred on the pivot, so only the plane test surface creates a moment; weights on a lever arm balance it and a panel scale shows the water head.

Applications and Experiments for the Center of Pressure Apparatus
With this apparatus, the hydrostatic thrust and the position of the centre of pressure on a submerged plane can be found for both partial and full immersion. The balancing moment M is related to the water height h, and the equivalent moment or thrust is compared with theoretical analysis in fluid mechanics lab experiments.
- B.E./B.Tech civil and mechanical: centre of pressure on a vertical plane surface.
- Repeating the test with the plane inclined.
- Partly versus fully submerged planes.
- Diploma civil: thrust on gates and walls, with pressure across a gate face measured on the Sluice Gate with Tappings and seepage beneath model sheet piling and dams on the Permeability, Flow Nets And Darcy's Law tank.
Standard Scope of Supply
Each set comprises the vertical panel with head scale, the clear plastic quadrant tank, the lever arm with weight hangers, the smaller trimming tank, levelling feet and spirit level, non-toxic water dye and a syringe. The quotation confirms the set of weights supplied and lists any optional accessories.
Packing, MOQ and Lead Time
Price requests can be for one unit or for a set per student group. The quotation you receive lists packing, delivery time and price for exactly that quantity, and further engineering lab equipment in India from the hydrostatics and fluid mechanics range can join it.

Frequently Asked Questions
Why does the quadrant have curved sides?
The curved surfaces share their axis with the pivot, so the fluid pressure on them passes through the pivot and exerts no moment. The measured moment therefore comes only from thrust on the plane surface.
How is the apparatus prepared before readings?
It is levelled with the feet and spirit level, a vertical or inclined plane is chosen, and the quadrant is balanced using a weight hanger and the smaller trimming tank before water and weights are added.
Is Science Lab Supplies the manufacturer or a trader?
The quadrant, its panel and lever arm all come out of Science Lab Supplies' own factory in Saha, Ambala, India, and each quotation for the apparatus is drawn up by that factory rather than by a reseller.
What are the dye and syringe for?
The non-toxic water dye makes the water levels against the quadrant and scale easier to see, and the syringe adds or removes small amounts of water accurately while the moment is being balanced.
