i) An open channel of trapezoidal cross section, 2.5m at the base and sides inclined at 60° to the horizontal has a bed slope of 1 in 500. It is found that when the flow is 1.5 m³/s, the depth of the water in the channel is 0.5 m. Determine the roughness coefficient of this channel. ii) Calculate the flow rate when the depth of flow in the channel above increased to 0.7 m. iii) Evaluate Reynolds Number and hence comment on the type of flow in the channel iv) Calculate the Specific Energy along the centre of the channel.
