Fluid Pressure Apparatus, Hydraulic Press
Product Code : EL-POM-10379
Quick answer: The hydraulic press fluid pressure apparatus shows that pressure applied to a confined liquid is transmitted through it, so a small force on a narrow piston can support a larger load on a wide one. Plated cylinders of different diameters are joined at the base, and each piston carries a disc for loading masses. Lab Exports manufactures it in Delhi for schools, colleges and universities.

| Principle shown | Transmissibility of fluid pressure (Pascal's principle) |
How the hydraulic press experiment is done
By Pascal's principle the pressure in the confined liquid is the same throughout, p = F/A. A force F1 on a piston of area A1 therefore produces a force F2 = F1 x A2/A1 on a piston of area A2. When masses are placed on the loading discs so that the pistons balance, the loads stand in the same ratio as the piston areas, which is the square of the ratio of their diameters.
The trade-off is distance: the small piston moves further than the large one, so the work done on each side is the same apart from friction. This is how a hydraulic jack, a vehicle lift or a hydraulic press multiplies force.
- Fill the cylinders and connecting tube with water, working the pistons to drive out trapped air.
- Place a known mass on the loading disc of the narrowest piston.
- Add masses to the disc of a wider piston until the two pistons balance.
- Measure the piston diameters and compare the ratio of the loads with the ratio of the areas.
Key features
- Cylinders of different diameters, so force multiplication can be measured as well as seen
- Pistons with circular loading discs for adding masses
- Cylinders joined by a tube at the base, so the same pressure acts on every piston
- Plated finish on the cylinders
- Base-mounted assembly that stays steady while masses are added

Frequently asked questions
What principle does the hydraulic press apparatus demonstrate?
It demonstrates Pascal's principle, the transmission of pressure through a confined liquid, and how that pressure multiplies force on a larger piston.
What are the loading discs for?
Each piston carries a circular disc on which masses are placed, so the loads that balance on different pistons can be compared.
Why are the cylinders different sizes?
The same pressure acting on pistons of different areas gives different forces, which is the working principle of a hydraulic press.
