If B and d are the bed width and depth of a channel in meters, the combined losses due to evaporation and seepage in cumecs per kilometer length of the channel, is
If B and d are the bed width and depth of a channel in meters, the combined losses due to evaporation and seepage in cumecs per kilometer length of the channel, is Correct Answer $$\frac{1}{{200}} \times {\left( {{\text{B}} + {\text{d}}} \right)^{\frac{2}{3}}}$$
