Fluid mechanics in a closed system

Fluid Mechanics in a Closed System

Pascal’s Law states in a closed system, an increase of pressure at any point will produce an equal increase in the pressure at every point in the liquid.

Difference between force and pressure:

Pressure is exerted on a unit area.


Fluid mechanics in a closed system

Consider a glass flask. Fill it to the top and insert stopper into the neck. If you hit the top of a 1 sq in stopper with an 18 lb force, what pressure is exerted on the 25 sq. in bottom?


Fluid mechanics in a closed system

Pressure is transmitted through a liquid.

If the system is closed with equal piston area, we will have equal inputs and equal outputs.


Fluid mechanics in a closed system

If the system is “U” shaped, the direction of the force can be changed.

One force down = One force up

The shape of the container has no effect on the pressure in it. We could connect the equal piston through a “small hose” and move our equal force anywhere we want it.


Fluid mechanics in a closed system

Suppose the pistons have different areas. Then the forces are different and the distance moved are different.

If we connect two pistons in a closed system, the distance moved is inversely proportional to their areas. Volume remains constant.
