Answer 1

Answer:

Step-by-step explanation:

Volume of pool = 70*44*3 m

                          = 9240 m^3

Diameter of pipe = 35 cm = 0.35 m

Speed of water in pipe = 6 m per second

Volume of water filled by pipe in 1 second

= π r^2h

= π 0.35*0.35*6

= π 0.735 m^3 = 2.31 m^3

Time taken to fill the pool = 9240/2.31

= 4000 seconds

= 4000/60 minites

= 66.667 minutes
