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 is a standard hydrostatics practical in civil and mechanical engineering courses. Science Lab Supplies builds it at its manufacturing plant, Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sells it directly to colleges, polytechnics, contractors and distributors.
Specifications
A vertical panel holds a clear plastic quadrant tank. Its curved sides are centred on the pivot, so pressure on them creates no moment and only the plane test surface does. Weights on a lever arm balance that moment, a panel scale shows the water head, and engraved lines set the plane vertical or angled.

Applications and Experiments for the Center of Pressure Apparatus
The apparatus is used to find the hydrostatic thrust and the position of the centre of pressure on a submerged plane, for both partial and full immersion. Students relate the balancing moment M to the water height h and compare results with theory, a core set of 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.
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.

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?
Students level it with the feet and spirit level, choose a vertical or inclined plane, then balance the quadrant using a weight hanger and the smaller trimming tank before adding water and weights.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures it. The quadrant, panel and lever arm are made at the company's factory in Saha, Ambala, India, which also prepares each quotation.
What are the dye and syringe for?
The non-toxic dye makes water levels easier to see, and the syringe adds or removes small amounts of water accurately.
