Answer
$2.23\times10^{7}\;Pa$
Work Step by Step
The difference between an absolute pressure and an atmospheric pressure is called the gauge pressure.
Therefore, the gauge pressure is given by
$P_{g}=\rho gh$
Substituting the given values
$P_{g}=1025\times9.81\times2.22\times10^{3}\;Pa$
or, $P_{g}=1025\times9.81\times2.22\times10^{3}\;Pa$
or, $\boxed{P_{g}=2.23\times10^{7}\;Pa}$
