Chapter 2, Problem 2.109(choose chapter or problem)
A thin 4-ft-wide, right-angle gate with negligible mass isfree to pivot about a frictionless hinge at point O, as shown in Fig.P2.109. The horizontal portion of the gate covers a 1-ft-diameter drain pipe that contains air at atmospheric pressure. Determine theminimum water depth, h, at which the gate will pivot to allow waterto flow into the pipe.
