To copmletely capture linear flow travelling along a gutter perpendicular to a curb inlet, the inlet must be of width:
To completely capture linear flow travelling along a gutter perpendicular to a curb inlet, the inlet must be of width::
<math>W=0.817Q^{0.42}S_{0}^{0.3}\left (\frac{1}{nS_{x}}\right)^{0.6}</math>
<math>W_T=0.817Q^{0.42}S_{0}^{0.3}\left (\frac{1}{nS_{x}}\right)^{0.6}</math>
Where the intention is to capture only a proportion of the flow, the ratio of flow entering the crub inlet may be calculated::
<math>R_c=1-\left ( 1-\frac{W}{W_T} \right )^{1.8}</math>
