where P is the pressure (Pa), F is the force (N) and A is the area (m2). [1]
Force unit can be determined by F= m*a, (mass*acceleration).
Volume pressure, known as the density can be used when determining the volume of the container.
p (rho) = m (mass) / V (volume). [2.]
Archimedes's principle states can be determined by for example a person goes bath and the waterspills over bathtub. The amount of spilled
water has the same volume than a person.
Physical formula is: P= p*h*g
P = p (rho) * h (height in metres) *g (gravitation force (9,81 m/s^2))
Pascal's law states that an increase in pressure at any point in a liquid causes a corresponding increase at every other point in the
liquid. [23.]
For example if pressing a cylinder on the other side and because of the water is solid, second cylinder will be pulled out upward.
This method is a common in for example car brakes.
