Answer
given,
Height of the lab, h = 5 m
Depth up to which it can withstand Pressure,D = 150 m
Pressure on the top of lab when it is placed at 150 m depth
[tex]P = P_a + \rho g D[/tex]
P_a is atmospheric pressure, 1.01 x 10⁵ Pa
density of the sea water = 1020 Kg/m³
[tex]P = 1.01\times 10^5+1020\times 9.8\times 150[/tex]
P = 1600 kPa
now, Pressure variance on the side of the contained at distance 'x'
[tex]Pressure\ variance = \rho_{sea}g(D +x)[/tex]
=[tex]1020\times 9.81\times (150+x)[/tex]
=[tex]10006.2 (150+x)\ N/m^2[/tex]
[tex]Pressure\ variance = 10(150 +x)\ kN/m^2[/tex]
