Question

At what depth will the pressure exerted on man be twice that of pressure at the surface of the water.

Answer 1

Answer:

10.2 m.

Pressure under water is given by the sum of atmospheric pressure and pressure of fluid. Thus, depth in water at which pressure will be equal to twice the atmospheric pressure is 10.2 m.

Answer 2

Pressure at depth d = 2× Pressure

at surface

Pa + dρg = 2×Pa

dρg = Pa

d = 1.013×10^5 Pa/1000kg m^-3 ×9.8

m/s^2

= 10.3 m

Where d is depth ,ρ is density of water,Pa is atmospheric pressure
