H.W.17/ This a butterfly valve (D = 12 ft) is used to control the flow in a 12 ft diameter outlet pipe in a dam. In the position shown, the valve is closed. The valve is supported by a horizontal shaft through its center. The shaft is located H = 60 ft below the water surface. What torque would have to be applied to the shaft to hold the valve in the position shown? H Water Butterfly valve Shaft A

A thin 6-ft-wide, right-angle gate with negligible mass is free to pivot about a frictionless hinge at point O, as shown in the figure below. The horizontal portion of the gate covers a 2-ft diameter drain pipe, which contains air at atmospheric pressure. Determine the minimum water depth, h, at which the gate will pivot to allow water to flow into the pipe. Width 6ft- Right-angle gate Hinge 39000 0. 4 ft Water 2ft-diameter pipe
