A 8

B 9

C 11

D 13

E 15

Bunuel :

the volume is given in inches and flow rate is given in ft ^3 per sec..

no conversion feet to inches given..

it seems that either flow rate is also in in^3 per sec

so answer would be 11 IMO C ..else if the flow rate is in ft^3 per sec then answer option is not given

Please check..
