Question

Pressure at a certain depth in pond is $6$ atm. Find the depth of the pond (in $m$)approximated to nearest integer.

Answer 1

Total pressure=atmospheric pressure+fluids pressure

$\therefore$fluids pressure=6 atm-1 atm=5 atm

$\Rightarrow \rho \times g\times h=5atm$

$\Rightarrow 1000\times 9.8\times h=5\times 101325\Rightarrow h=51.69m$

The depth of the pond maybe 51 m.
