1. Applications of
Pressure in
Liquids

2. Public Water Supply
System
A
B
PA > PB since A is at a greater depth
The water from a river or dam is pumped into a reservoir located at a high elevation.
The reservoir is placed at an elevated location so that the water will have sufficient
pressure to flow to consumers located at lower levels.
Normally, every home has a water tank above the roof for storage and to provide a
constant water pressure.

3. Construction Of Dams
The water at the bottom of the dam is at a higher pressure than at the top.
Hence, the wall of the dam has to be thicker at the bottom to sustain this greater
water pressure.

4. Blood
Transfusion
A bottle is hung at a higher position so that the liquid solution has sufficient pressure
to flow into the veins of the patient.

5. Thick Wall Built
in Submarine
The deeper the submarine submerge into the water, the greater the pressure exerted.
The submarine is built with thick wall to withstand enormous pressure at greater depth.
