A flownet for an earth dam on impervious foundation consists of 4 flow channels and 15 equipotential drops. The full reservoir level is 15 m above the downstream horizontal filter. Given that horizontal permeability is 9 x 10-6 m/s and vertical permeability is 1 x 10-6 m/s, the quantity of seepage through the dam will be
