Problem statements
  • 1.5.2. Demonstrate that Eq. (6.5) is dimensionally homogeneous. Q = C d A(2gh) 1/2
    Q = discharge (volumetric flow rate, i.e., volume per unit time),
    C d = discharge coefficient (dimensionless),
    A = an area,
    g = acceleration of gravity,
    h = a depth

    • 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
 
20 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.
 
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 trial-and-error 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 cross-section by hand or using EXCEL. Calculate A, P, R h , 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 .
 
23 From the textbook, solve: 10.14, 10.16, 10.20, 10.22  
24 From the textbook, solve: 10.25, 10.28, 10.30, 10.36
