water is flowing at the rate of 14km/hr
hence the length of the pipe is 15km = 15000m
diameter of pipe = 14cm
radius = 7cm = 7/100 m
dimensions of pond = 44m × 50m × 21cm
=44m × 50m× 21/100m
ATQ, vol. of pond = vol. of pipe × t ( time taken to fill 21cm of pond = t )
lbh = 1/3 πr²h
44×50×21/100 = 1/3× 22/7 × 7/100×7/100×15000 ×t
t = 2 hrs
