From the textbook, solve:
- 8.55 - Use (a) Moody diagram, (b) Haaland equation, (c) Swamee-Jain equation to calculate the friction factor f - show the different values of hf calculated using the three methods
- 8.67 - Use Haaland's equation for f in part (a) and Swamee-Jain's equation for f in part (b). Use an iterative procedure assuming f = 0.03 to get started.
- 8.69 - Use Swamee-Jain's equation to calculate f. Use an iterative procedure assuming f = 0.03 to get started.
- 8.98 - Use Haaland's equation for f. Use an iterative procedure assuming f1 = f2 = 0.03 to get started.

From the textbook, solve:
- 8.76 - Notice that the friction factor is given and assumed constant. Thus, the solution should be easier than the trial-and-error case shown in the example from Lecture 27.

From the textbook, solve:
- 10.3 - NOTE: In part (b), you're calculating the normal depth
- 10.10 - Summarize results in a table of Q -vs- y and produce a plot of these data.
- 10.13 - Summarize results in a table for b = 2, 4, 8, 12, 16, and 20 ft in order to produce the plot.
- 10.33 - Plot the cross-section by hand or using EXCEL. Calculate A, P, Rh, and Q for each value of y in the table. Plot Q -vs- y and interpolate the value of y from the graph (or table) for the required value of Q. Follow example in pages 19 and 20 of this handout.
