Volume of the water required for rising the water level by 4.5 metre
= 7 × 4 × 4.5 = 126 m3
Time in which the tank needs to be filled = 6 hours and 18 minutes
=6+1860=6+1860 hr =6+310=6+310 hr =6310=6310 hr
Therefore, amount of water that needs to be supplied by the pipe in 1 hr
126(6310)=126×1063=20126(6310)=126×1063=20 m3/hr
Area of the pipe = 5×4 = 20 cm2 = 0.002 m2
Required speed of the water = 200.002200.002
= 10000 m/hr = 10 km/hr
I hope u understood
u can solve it
