(b) The drainage area of a town is 20 hectare. The classification of the surface of its area is as follows:
Percentage of total surface area | Type of surface | Runoff coefficient
25 | Hard pavement | 0.85
25 | Roof surface | 0.80
15 | Unpaved street | 0.30
25 | Garden and lawns | 0.15
10 | Wooden area | 0.10
If the time concentration for the area is 30 minutes, find the maximum runoff. Use the following formula for intensity of rainfall: $R_i = 900 / (t + 60)$
