How to Prove Pressure (P) = hdg? - Pressure Proof
Liquid pressure is the pressure exerted by the liquid per unit area of the surface. Liquid pressure is defined by one important formula i.e. p = hdg.
In this formula, 'p' stands for 'liquid pressure', 'h' stands for the height or depth of the liquid, 'd' stands for the density of the liquid and 'g' stands for acceleration due to gravity.
Prove: P = hdg
Consider a liquid of density(d) is kept in a container with the base area (A) and the height (depth) of the liquid is (h) as shown in the figure.
We know that,
Pressure (P) = Force (F) /Area(A) [ General formula of Pressure ]
From the above formula P = hdg, we can conclude the following things:
Factors affecting liquid pressure:
- Depth of liquid (h)
- Density of liquid (d)
- Acceleration due to gravity (g)
The pressure is one of the important chapters from Physics for Class 10. In class 10, we mostly focus on liquid pressure and hydraulic than other types of pressure. So, this proof of P = hdg is the most important for class 10 board preparation for every batch that would be appearing in the class 10 finals examination.

We hope that this solution will help you understand the proof of P=hdg more clearly.
ReplyDeleteThank u but I am reading it in class 8. Keep working😊
ReplyDeleteWe are happy we could help you.
Deleteit was helpful indeed
ReplyDeleteWe are delighted we were of your help.
DeleteCan u explain it just by using the diagram
ReplyDeleteThis was very helpful indeed.
ReplyDeleteYou're welcome
DeleteIt was helpful
ReplyDeleteWhat will be the unit of p in CGS?
ReplyDeleteSI unit of Pressure is N/m². So, CGS unit of Pressure is dyne/cm².
DeleteThnx
ReplyDeleteWhat is f=ma?
