7. Water flows at 32 m3/s through a rectangular channel 8 m wide and 4 m deep. If the flow velocity is 1.2 m/s, calculate the depth of flow in the channel. If this channel expands (downstream) to a width of 10 m and the depth decreases by 0.5 m from the upstream depth, then what is the flow velocity in the expanded section?
