WebStep 4 Calculate the total gutter flow using the equation: Q = Qs/(1 - Eo) (11.6) Where: Q = gutter flow rate, m3/s Qs = flow capacity of the gutter section above the depressed section, m 3/s Eo = ratio of frontal flow to total gutter flow (Qw/Q) (Q = 0.085 / (1-0.46) = 0.157 m3/s) Step 5 Calculate the gutter flow in width (W), using equation 11.5. WebManning's equation is rearranged to quantify friction losses. Equation 7 can be used to determine the head loss through a culvert. If bends occur along the length of the culvert, then these losses must also be included in Equation 7. Equation 7: Where: K x is an exit loss coefficient; n is Manning's roughness coefficient; floriani software price
