1. An aquifer with a total volume of 100000 metre3 has of porosity of 10% and specific retention of 5% the aquifer gets replenshed to its maximum capacity everyday. what would be the maximum pumping rate at which water can be withdrawn for a period of five hours from the aquifer to maintain its specific yield capacity?

Dear Student,

The solution is as follows-

Total Volume = 106 m2
Porosity = 10% = ({10 over 100}) = 0.1
Specific retention = 5% = ({5 over 100}) = 0.05%
P = S.Y + S.R
0.1 = S.Y + 0.05
0.1 - 0.05 = S.Y.
0.05 = S.Y.
Pumping rate = ({1000000m^{6} over 5hr}) x S.Y.
= ({1000000m^{6} over 5hr})( imes{0.05 over 100})
= 10,000 m3/hr.
