A column of water 1 ft high exerts a pressure of ____.

Question

Quizplus · Accepted Answer

The pressure exerted by a column of water is given by the equation P = ρgh, where ρ is the density of water (62.4 lb/ft³), g is the acceleration due to gravity (32.2 ft/s²), and h is the height of the column. Therefore, P = (62.4 lb/ft³) x (32.2 ft/s²) x 1 ft = 2,010.48 lb/ft². Converting to psig (pounds per square inch gauge) by dividing by 144 (the number of square inches in a square foot) and subtracting atmospheric pressure of 14.696 psia, we get P = (2,010.48 lb/ft²)/(144 in²/ft²) - 14.696 psia = 0.433 psig.
