How many litres per hour does it take to fill a tank?
Pipe takes 18 hrs to fill the tank and it takes 26 hrs when the leak operates. Let’s assume that the total capacity of tank is 234 liters. (LCM of 18 and 26 is 234) The efficiency of pipe is 234/18 = 13 lts per hr.
When a tap fills 4 litres of water per minute it fills 240 litres per hour and the leak drains 1/12 of the tank. As we know in 1 hour 240 litres of water is filled which is 1/60th of the tank. A tank has a leak which would empty it in 8 hours.
