Physics - Fluid Question with Solution | TestHub

The absolute pressure at a depth $h$ below the water surface is given by $P=P_0+\rho gh$, where $P_0$ is the atmospheric pressure.

Given:
$P=100$ atm $=100\times 10^5$ Pa
$P_0=1$ atm $=1\times 10^5$ Pa
$\rho =1000$ kg m${}^{-3}$
$g=10$ m/s${}^2$

Substituting the values into the equation:

$100\times 10^5=1\times 10^5+1000\times 10\times h$

$99\times 10^5=10^4\times h$

$h=\frac{99\times 10^5}{10^4}$

$h=990$ m

Answer: $990$ m
