2.2. The upstream conditions are the same as in Exercise 2.1 with a smooth contraction in width from 10 ft to 9 ft and a horizontal bottom. Find the depth of flow and change in water surface elevation in the contracted section. What is the greatest allowable contraction in width so that choking is prevented? (Head loss coefficient = 0.)

2.3. The upstream conditions in a rectangular channel are the same as in Exercise 2.1 with a smooth contraction in width from 10 ft to 8 ft. How much should the channel bottom drop to maintain a constant water surface elevation through the transition? (Head loss coefficient = 0)
