Answer:
2800ft³
Explanation:
The formula used to calculate the volume of one tank is:
Vt = Q x t
We have Q as
Q = (3x10⁶gal/d)/3 tanks
Q = 1x10⁶gals/d per tank
To get volume of one tank
[(30min)x(1x10⁶)x(0.1337)]/1440 min
= 30x1000000x0.1337/1440
= 4011000/1440
= 2,785ft³ or 2800ft³
In conclusion, 2800ft³ is the design volume, in cubic feet, of one of these tanks with detention time as 30 minutes
