Question

3. The figure shows a spillway which is essentially a dam that holds back water until it reaches a certain depth, at which point the water "spills" over the top. You may assume the pressure is distributed hydrostatically at stations 1 and 2. You may also assume that the width of the spillway is constant everywhere. The density of water is 1000 kg/m2 Control Surface Streamline 5 m 0.7m V/2 (a) Find the velocities, Vi and Va. Note that you may consider the surface of the water to be a streamline (b) Find the force per unit width acting on the spillway.
