Question

a cylindrical tank full of water is emptied by a pipe at the rate of 225 litres per min how much time will it take to empty the half the tank if diameter of its base is 3m and its height is 3.5 m π =22/7

Answer 1

Volume of cylidrical tank
= 22/7 * 1.5 * 1.5 * 3
= 24.75 m cube.

Capacity of cylindrical tank
= (24.75 * 1000)L
= 24750 L.

Half the capacity of tank
= 24750/2
= 12375 L.

Time taken for the tank to get half empty
= (12375/225) minutes
= 55 minutes.
