Expert Solution
Step 1

The pressure of the water at the top surface of the tower is

P=P0+ρghP0-atmospheric pressureρ-dinstity of the waterh-height of the water level.here P0=14.7 psi=1 atm=101352.9 Paρ=1000 kg/m3h=12 ft=3.6576 mP=101352.9+1000×9.8×3.6576=137197.38 Pa

The pressure at a height h is 137197.38 Pa
