Determine the impacted conditions for benzene infiltration for a region containing Troop sand that experiences a heavy storm over 3 hours, in terms of the mean flow rate, and the maximum, minimum and average velocity of benzene infiltrating? Assume the rainfall occurs over an area that is 100m2 (normal to the rainfall direction) and the Troop sand density 1 kg/L, porosity 20%, and foc 0.02). averagef over 3 hr 5.12
