# 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. Find the rise in the level of water in 30 minutes?

Answer :

Given,

Internal diameter of circular pipe = 2 cm

So, radius of pipe =

Rate of flow of water through pipe = 6 m/s

Radius of base of cylindrical tank = 60 cm

So, volume of water flows through pipe in 1 second = πr^{2}h =

Volume of flows in 30 minute (30×60) second =

Let rise of water level in cylindrical tank = h m

So, volume of water collected in tank in 30 minute =

=

= h =
