Unformatted text preview: Use the Christensen experimental method for the depth. The graph for Christensen’s method can be approximated by the equation below. 0916 . 5003 . 1 6336 . 1 * 9655 . 2 3 + + - = Qfull Qactual Qfull Qactual Qfull Qactual Dfull Dactual Note: Remember that the minimum pipe diameter to be used in the sewers is 8” and the minimum velocity of the water in the pipes when flowing full is 2fps. If you work this problem in Excel, you can email me your spreadsheet but make sure the equations used are written somewhere in the spreadsheet and your work is very organized. 1 2 4 3 A B EL=130' EL= 110' EL= 150' EL= 130' EL= 122' EL= 86' EL = Elevation Figure 1.
