what is the absolute pressure at a depth of 3 m in a swimming pool?

Question

where is the answer :o

Answer 1

Assuming that the pool is full of water with density 1000 kg / m^3, the pressure is

P(atmospheric) + p g h

where P is the atmospheric pressure at the surface
p the density of water
g the local acceleration of gravity
h the depth (in this case, 3 m)

Answer 2

3m = 3,000mmH2O ÷ 13.6(SG of Hg) = 221mmHg + 760
= 981mmHg Absolute pressure.

(981/760) x 14.7 = 19psia)

Answer 3

4.265psig

Absolute pressure will be 18.965 psia <<<<<<-----answer

That's because you add 14.7psi for atmospheric pressure.
