Document Summary
1. 1 a round tank 2 m in diameter is filled with oil (rd = 0. 83) to depth of 1. 5 m. calculate hydrostatic force at the base of the tank. (ans: 38. 37 kn) 1. 2 (a) a rectangular culvert 2. 1 m wide and 1. 8 m high discharges to a river channel as shown in fig. At the end of the culvert is a vertical flap gate which is hinged along its top edge, the gate having the same dimensions as the culvert. During the flood the river rises to 3. 5m above the hinge. 2 (b) a circular gate, also hinged at the top, hangs vertically at the end of a pipe discharging to the river. The gate has a radius of 0. 5 m, and during flood the hinge is 3. 5 m below the water surface. What is the force exerted by the floodwater on the gate, and at what depth from the surface does it act? (ans.
