A field of 3 acres with a runoff coefficient of 0.55 and a field of 5 acres with a runoff coefficient of 0.75 experience a rainfall intensity of 5.5 in/hr. If the runoff drains to a common collector, the peak flow in the collector is most nearly;
Answer:
107,768 ft³/hr
Explanation:
Given that :
FIELD A:
Runoff Coefficient (C1) = 0.55
Field size (s1) = 3 acre
FIELD B:
Runoff Coefficient (C2) = 0.75
Field size (s2) = 5 acre
Rainfall intensity (I) = 5.5 in/hr
We need to convert ;
Field size to ft²
1 acre = 43560 ft²
s1 = 3 acre = 43560 * 3 = 130,680 ft²
s2 = 5 acre = 43560 * 5 = 217,800 ft²
Rainfall intensity to ft/hr
1 inch = 0.0833 ft
5.5 in/ hr = (0.0833 * 5.5) ft/hr = 0.45815 ft/hr
Peak flow :
(C1 * s1 * I) + (C2 * s2 * I)
(0.55 * 130680 * 0.45815) + (0.75 * 217800 * 0.45815)
32929.0731 + 74838.8025
= 107767.8756 ft³/hr
