What is the total hydrostatic force on the walls of a cylindrical water tower 50' high and having a radius of 18'? [The density of water is 62.4 lbs/ft³.] A) 79,394,000 lbs B) 176,000 lbs C) 8,822,000 lbs D) 17,643,000 lbs

Question

Quizplus · Accepted Answer

The hydrostatic force on the walls of a cylindrical water tower can be calculated using the formula F = ρghA, where F is the force, ρ is the density of water, g is the acceleration due to gravity, h is the height of the cylinder, and A is the base area of the cylinder.

In this case, F = 62.4 x 32.2 x 50 x π x 18^2 = 8,822,000 lbs (rounded to the nearest thousand). Therefore, the correct answer is choice C.
