Longhorn Dam is a dam built on the Colorado river that creates the Lady Bird Lake in Austin, TX. The water goes up to a height of 11 m and covers a length of 154 m on the dam, creating a rectangular barrier. In order to compute the hydrostatic force upon the dam, we can use the pressure of water at depth h where rho is the density of water and g is gravity. Typically, in the month of August every year, the water temperature of Lady Bird near the dam is about 85° F, which gives p970.56 Kg/m3.
Given that hydrostatic force is F pA for constant pressure along an area A, calculate the differential of force dF along a horizontal strip on the dam at depth h. Assume that the dam's contact surface with the water is rectangular.
dF- 9511.5 dh N/m
dF 1464769.2 dh N/m
dF 970.6 dh N/m
