Two drums, A and B of the same size and height, are taken with liquid in them.
i. What will be the difference in liquid pressure on their bases if drum A is
completely filled, and drum B is filled half with the same liquid and kept at
the same
place? Also, give a reason.
ii. What will be the difference in liquid pressure on their bases if both drums (A
and B) are filled with water completely, but one of them is kept in Lumbini
and another in Pokhara? Why?
iii. What will be the difference in liquid pressure on their base if drum A is filled
with water and drum B is filled with salty water, and both of them are kept
in Biratnagar in the same position? Why?



Answer :

Final answer:

The pressure on the walls of the drum would increase when it is filled with petroleum ether to the top.


Explanation:

a. Determine the amount of pressure applied to the walls of the drum if the petroleum ether fills the drum to its top:

  1. Pressure on walls: If the drum holds 800 liters, equivalent to 0.8 m³, the pressure would increase due to the additional volume pressing against the walls.
Key points: pressure, walls, petroleum ether
