Solve part 1  using the Moody diagram only

Solve part 2 as indicated in the problem statement

Solve part 3 as indicated in the problem statement

From the textbook, solve:

8.55  Use (a) Moody diagram, (b) Haaland equation, (c) SwameeJain 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 SwameeJain's equation for f in part (b). Use an iterative procedure assuming f = 0.03 to get started.

8.69  Use SwameeJain'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.


21

From the textbook, solve:

8.76  Notice that the friction factor is given and assumed constant. Thus, the solution should be easier than the trialanderror case shown in the
example from Lecture 27
.


22

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 crosssection by hand or using EXCEL. Calculate A, P, R
_{
