Calculate the water pressure at the bottom of a tank whose length, width, and depth are 2m,  1.5m, and 1m respectively. The density of water is 1000kgm⁻³.

Given : 
Height (h)=1m,
Density (d)=1000kgm⁻³,
Acceleration due to gravity (g)=9.8ms⁻²
Since pressure depends only on the depth of the liquid, therefore,
Pressure (P)=hdg
=1m×1000 kgm⁻³×9.8ms⁻²
P =9800 Nm⁻²

Therefore, water will exert 9800 Nm^-2 pressure at the bottom of the tank.
