For the information above, pressure of liquid just depend on 2 variable :

Depth (h),

that have relation pressure ~ depth

Density ()

that have relations pressure ~ density

We can write formula :

We can write formula :

p ~ .h or

p = .g.h

which pressure (p), depth (h), density ( ), and gravitation (g)

A body floats in water at a depth of 20cm. If the density of water is 1,000 kg/m3 and the acceleration due to gravity is 10 m/s2, then what is the hydrostatics pressure at the place where object floats?

Pressure applied to an enclosed liquid is transmitted to every part of liquid, whatever the shape of liquid.

In a hydraulic system fluid is confined in two connecting chambers.

In a hydraulic system fluid is confined in two connecting chambers.

Each chambers has a piston that is free to move.

A 50 newton force is exerted on the small piston a hydraulic system. The cross-sectional area of small piston is 0,05 m2. What is the magnitude of the weight that can be lifted by the large piston, which has a surface area of 0,2 m2?
