The force of one foot of water column equals

Question

Quizplus · Accepted Answer

The pressure exerted by a column of fluid is equal to the product of the height of the column, the density of the fluid, and the acceleration due to gravity. For water, the density is approximately 62.4 pounds per cubic foot, and the acceleration due to gravity is 32.2 feet per second squared. Thus, the pressure exerted by one foot of water column is:

1 ft x 62.4 lb/ft³ x 32.2 ft/s² = 2,008.32 lb/ft²

To convert this to psi, we divide by 144 in²/ft²:

2,008.32 lb/ft² ÷ 144 in²/ft² = 13.89 psi/ft

Finally, we divide by 32.2 ft/s² to get the pressure in psi per foot of water column:

13.89 psi/ft ÷ 32.2 ft/s² = 0.433 psi/ft

Therefore, the force of one foot of water column equals 0.433 psi.
