Question 4 The depth of uniform flow in a 3 m wide straight rectangular channel, for a discharge of 10 m2/s, is 2.2 m. The water flows around a 90° bend with an inner radius of 5 m, as shown in Figure 3. Assuming that the flow through this bend approximates a free vortex, calculate the depth of water at its inner and outer radii. Ignore the bed slope and energy losses.
