3. Textbook problem 7.28. Solve using manual means (only). Draw the cross-section to scale on engineering paper or AutoCAD (use 1:1 H:V scales). The drawing should take up most of the page (landscape orientation required) and must use at least three flow channels; you may find the use of more channels easier. Since all of the following calculations will be based on this drawing, take your time. Double check that your drawing follows the rules of flow net construction, and look at examples in the text for guidance (Pgs 309-318). Hint: you may use partial equipotential drops; however, you must indicate where these are in your drawing, what fraction of a drop you are using, and it must be drawn to scale. 7.28 Develop a flow net for the case shown in Fig. P7.28 using either manual methods or flow net software. Assume three or four flow channels. FIGURE P7.28 (Adapted from Taylor, 1948.) 15 m 3 m 45 m Cutoff wall 9 m 30 1.5 m
