Best answer

Solution: Radius of pipe = 10 cm = 0.1 m, length = 3000 m/h

Radius of tank = 5 m, depth = 2 m

Volume of water in 1 hr through pipe

10 surface area volume exercise solution

Volume of tank

10 surface area volume exercise solution

Time taken to fill the tank = Volume of tank/Volume of water in 1 hr

10 surface area volume exercise solution
