Q3:A rectangular channel having a width of 3.0 m undergoes a transition. The width is changed to 2.5m and the bed has a smooth drop of 0.2 m. This transition causes a drop of 0.1m in the water surface between the upstream and downstream of the transition. The depth of flow in the upstream channel is 2.0m. Assuming no loss of energy in the transition, estimate the discharge in the channel. B₁= 3.0 m X₁ V Flow V Plan B₂= 2.5 m 0.1 m 3/2 0.2 m

causes a drop of 0.1m in the water surface between the
upstream and downstream of the transition. The depth of
flow in the upstream channel is 2.0m. Assuming no loss
