    V = Q1*12*60

    V = (Q1-14)*96*60

    84Q1 = 1344

    Q1 = 1344/84 = 16 lpm

    V = Q1*12 = 16*12 = 192 liters

    If the answer is x:

    The incoming pipe is bringing x/12 litres per minute.

    The outgoing pipe is losing 14 litres per minute.

    So the overall input rate is (x/12) - 14 litres per minute.

    After 96 minutes, the total water input is 96((x/12) - 14) = 8x - 1344 = x

    8x - x = 1344

    7x = 1344

    x = 1344/7 = 192
