2.43. The 2-m-diameter pipe illustrated in Figure 2.58 drains water from a reservoir, where the crown of the pipe is 3 m below the surface of the reservoir. If the pipe entrance is covered with a 2-m-diameter gate hinged at A, determine the magnitude and location of the net hydrostatic force on the gate. What torque would need to be applied at A to open the gate? Figure 2.58 Submerged gate Wall 3 m Reservoir Gate A Pipeline 2 m
