Question

What is the total pressure on the earth back of a scuba diver in a lake at a depth of 8m , if the atmospheric pressure is equal to 1.01 X 10^5 and density of water is 10^-3 kgm^-3​

Answer 1

ANSWER

Given : h=10m, ρ=1000kg/m

3

, g=10m/s

2

Pressure on swimmer = pressure of atmosphere + pressure of water

=1atm+ρgh×10

−5

atm

=1atm+1000×10×10×10

−5

atm

=2atm
