1. A channel of symmetrical trapezoidal section, 900 mm deep and with top and bottom widths 1.8 m and 600 mm respectively, carries water at a depth of 600 mm. If the channel slopes uniformly at 1 in 2600 and Chézy’s coefficient is 60 m1/2 ·s−1, calculate the steady rate of flow in the channel.
2. An open channel of trapezoidal section, 2.5 m wide at the base and having sides inclined at 60◦ to the horizontal, has a bed slope of 1 in 500. It is found that when the rate of flow is 1.24 m3 ·s−1 the depth of water in the channel is 350 mm. Assuming the validity of Manning’s formula, calculate the rate of flow when the depth is 500 mm.
