Q.) water is flowing through a cylndrical pipe of internal diameter 2cm into a cylindrical tank of base radius 40cm, at the rate of 0.4m/sec. determine the rise in the level of water in the tank in half an hour??

Given, internal diameter of cylindrical pipe = 2 cm

So, radius of cylindrical pipe (r) = 2/ 2 = 1 cm

And,

Radius of cylindrical tank (R) = 40 cm

Let level of water rise to the height of h cm.

Thus, 

Now,

Volume of cylindrical tank = Volume of water flown out in half an hour

Hence, level of water rise to the height of  45 cm.
