Question 1169063: A tank containing 50 litres of water develops a leak and loses water at a constant rate. After 20 minutes it contains 40 litres. After a further 30 litres the tank is 5% of it's full capacity. Determine the tank capacity?
Answer by htmentor(1343) (Show Source): You can put this solution on YOUR website!
Let V = the tank capacity
The leak rate is given by (50 - 40)/20 = 0.5 l/m
Thus it takes 30/(0.5) = 60 m to lose 30 litres more
Thus, the remaining volume of water = 50 - 10 - 30 = 10 l
If this is 5% of the capacity, the total capacity is 200 litres
