Introduction
Pressure is force acting per unit surface area.
Pressure is measured in Nm2
or Pascals.
In our lives we encounter different types of
‘pressure’!
Did you know that pressure is incorporated into a
lot of our daily activities!
Do you know that some of our basic commodities
such as water and transportation are supplied to
us using pressure!

Characteristics of Pressure in Fluids
1) Pressure in fluids is dependent upon density,
gravity and depth below the surface the fluid.
2) Pressure increases with depth below the
surface of a liquid.
3) Pressure acts equally in all directions at a
certain point below the surface of a liquid.
4) Pressure is transmitted uniformly and equally
throughout a confined fluid.

Suction cup
The suction cup has some air trapped , whose
pressure is lower than atmospheric pressure on
the outside. The atmospheric pressure pushes it
against the surface and it sticks to the surface
and stays in place.

Hydraulic Car braking system
When someone steps on
the brake pedal (2), the
piston (3) exerts pressure on
enclosed liquid (4) which
transmits the pressure to a
larger piston (5). A larger
force is created which
pushes the brake pad (7)
against the wheel disc (8)
and the car stops.

A Yes. The saline solution is always elevated, so the pressure at the
bottom of bag will be great. The increased pressure is transmitted
through the fluid in the tubing to the ‘butterfly’ inserted into the
skin. A large force is exerted on the blood vessel greater than the
force of the blood moving around and so the saline solution enters
the blood.
