Question

8. (12 Points) Sketch a specific energy diagram and show Points 1 and 2 for each of the following cases (i.e., you should have one specific energy diagram for Case I and one diagram for Case 2 which is on the next page). You must write out the energy balance equation to receive full credit. ase a. Channel with a gradual increase in channel width from B to B2 (see b. c. d. diagram) Point 1 (upstream) condition is super-critical flow Neglect the change in slope and head loss How would the depth change at Point 2 if you included head loss? Show on the specific energy diagram how you found your answer Plan View II Case I a. Channel with a step decrease Az in the bottom elevation (see diagram) b. Point 1 (upstream) condition is sub-critical flow c. Constant channel width d. Neglect headloss e. How would the depth change at Point 2 if you included head loss? Show on the specific energy diagram how you found your answer Vl Az Elevation View
