Find the gauge pressure (in psi) at the bottom of a freshwater swimming pool that is 19.4 ft deep.

Answer 1

h= 19.4 ft

h = 5.91m <== 1 ft= 0.3048m

ρ = 1000 kg/m³ <== density of water

Guage Pressure at the Bottom of the pool can be represented by:

P= ρ(g)(h)

P = 1000 kg/m³ (9.81 m/s²) (5.91 m)

P = 57977.1 N/m² <== 1 psi = 6,894.7528 N/m²

P = 8.409 psi

I hope this helps!
