A hemispherical tank of radius 1.75 m is full of water . it is connected with a pipe which empties it at rate of 7 litre per second . how much time will it take to empty the tank completely ?
Given: Radius of hemispherical tank (R) =1.75m
Volume of hemispherical tank
Now,
Time taken to empty 7 L = 1 sec
Hence, the time taken to empty the tank completely is 26.7 minutes approximately.
