Question

Find the gauge pressure (in psi) at the bottom of a freshwater swimming pool that is 17.4 ft deep.

Answer 1

Gauge pressure is absolute pressure - atmospheric pressure.

You should assume that you are dealing with a 1"X1"X208.8"(17.4') volume of water because you need the pressure in psi. This is because you are not given any specific volume of water.

Use this formula: P=FA, A=1in², F=ma. Mass of water = Density of Water(ρ) X Volume of Water(1"X1"X208.8").
