Question

A swimmer is swimming in a swimming pool at 60 m below the surface of the water. Calculate the pressure on the swimmer due to water above.
(Density of water 1000 kg/m3, g = 9.8 m/s2)

Answer 1

Answer:

Let atmospheric pressure =P

o

=1.05×10

5

Pa

Pressure 10m below surface of lake,

P=P

o

+ρgh

=1.05×10

+1000×9.8×10

−1.99×10

5

Pa

=2 atm (ρ→ Density of water =1000 kg/m

3

, g=9.8m/s

2

h→ Depth=10m).
