Enter the liquid pressure and the cross sectional area of a hydraulic cylinder to calculator the force acting on that cylinder due to the liquid pressure.
Hydraulic Pressure Formula
The following formula is used to calculate the force acting on a hydraulic piston that is be subjected to a pressure.
F = A * P
- Where F is the force (Newtons)
- A is the cross sectional area (m^2)
- and P is the pressure (pascals)
This formula is derived from the laws of fluid dynamics. This can be further explored in Pascal’s principle which states that if a pressure if applied to a container of liquid that pressure is transmitted everywhere in that container.
This is the fundamentals of hydraulics. If you have one piston with a large area and apply a pressure P, that pressure is transmitted equally through the container. Therefore, if you then have another piston with a much smaller area, the same pressure is applied to that area, but the force is much greater since the values are directly proportional.
