Where is water pressure greater, at a depth of 1 m in a large lake or at a depth of 2 m in a small pond? Explain

Dear Student,

The pressure of the water does not depend on the area of the surface of the water body. The pressure experienced at a depth in a water body only depends on the depth and not on the size of the water body as Pressure = Density x g x h
Density of water = 1000kg/m3
g=9.8m/s2
So, pressure at a depth of 1m will be ,
P=1000 x 9.8 x 1
Therefore P = 9800 Pa
Pressure at a depth of 2m will be 
P=1000 x 9.8 x 2
Therefore, P = 19600 Pa 
​​​​​​Hence the pressure at 2m depth will be double than the pressure at 1 m depth.

Dear Student,
The answer to this question will be-

The size of the water body has no effect on the pressures experienced at depth in any water body. Thus at 1-meter depth in a large lake or in a pond the pressure is the same (1.1 bar). Likewise, at a depth of 2 meters in a large lake or small pond, the pressure is the same in both at (1.2 bar).
