A flow of 32 m2/sec occurs in an earth-lined trapezoidal channel having base width 3.0m, side slopes 1V:2H and n=0.022. Calculate the critical depth. Select one: O a. 1.902 m O b. 1.702 m O c 1.602 m O d. 1.502 m O e. 1.802 m
A channel has a bottom width of 350 m, depth 9 m and side slopes 1:2. If the depth is increased to 12 m by dredging, determine the percentage increase in velocity of flow in the channel. For the same increase in cross sectional area, if the channel is widened (instead of deepening), what is the percentage increase in the velocity of flow.
A channel has a bottom width of 300 m, depth 8 m and side slopes 1:1.5. If the depth is increased to 12 m by dredging, determine the percentage increase in velocity of flow in the channel. For the same increase in cross sectional area, if the channel is widened (instead of deepening), what is the percentage increase in the velocity of flow.
