Yea, i told you its a formula.. that is

Flow of water(volume of whole water) = Cross sectional (volume of the pipe) x Speed x time

can you solve the answer.. i am unable too. in Mark scheme they aren't using the speed in calculation :-\

I do  = 1512m3/ .00687m3 x .14m/s = 157205/ (60 x 60 x24) = 18.195 :(

according to mark scheme they do:
 1512m3/6870cm3 = 0.220087 x 1000000 = 220087/ (60 x 60 x 24)

i don't know why they at beginning divide a m3 with cm <-- impossible
then don't know why they multiply with 1000000 -.-
