Question

Water flows out through a circular pipe whose internal diameter is 2 cm, at the rate of 6 metres per second into a cylindrical tank, the radius of whose base is 60 cm. By how much will the level of water rise in 30 minu…

Accepted Answer

Option B. 3 m. Answer & Solution Answer: Option B Solution: Volume of water flown through the pipe in 30 min : & = [ ( × 0.01 × 0.01 × 6 ) × 30 × 60 ]m^3 & = ( 1.08 )m^3 Let the rise in level of water be h metres Then, & × 0.6 × 0.6 × h = 1.08 & h = ( 1.080.6 × 0.6 ) & h = 3\,m
