Answer to Question #294769 in Physics for Loie

Question

A dam is designed to withstand a pressure of 7840 lb/ft². Find the maximum depth of water that the dam could support.( A dam should not be built this tall—it should be designed to allow water to run over before reaching such dangerous condition.)

Answer 1

$$d=\dfrac{p}{\rho }=\dfrac{7840}{62.4}=125.6\text{ ft}.$$
