A pipe of diameter d can drain a certain water tank in 40 minutes. The time taken by a pipe of diameter 2d for doing the same job in :

An engine pumps out 950 litres of water in a minute.How much time will it take to pump out 13,96,500 litres of water?

A cylindrical pipe has inner diameter of 7cm and water flows through it at 192.5 litres per minute.Find the rate of flow in kilometres per hour.

A group of fire brigade personnel carried a right circular cylindrical tank filled with water and pumped out water at a speed of 420 metres per minute to put the fire in 40 minutes by three pipes of 2 cm diameter each. If the diameter of the tank is 2* 8 metres and its length is 6 metre, then calculate (a) what volume of water has been spent in putting out the fire and (b) hte volume of water that still remains in the tank .
