answer
circumference of the pipe
pi*diamater:which is 3.142*64m=201.88mm
the pipe discharges 2.05mm of water per second, so volume of warter to tank per second then the volume of tank is
v=pi*r^2=3.142*3900mm^2*23000=109910000 to find time
1sec =412.2304mm^3
109910000/412.2304
=26638.51
rounding off we get
=266638sec
