Water Flow Quiz

Water Flow Quiz explores the quiet importance of everyday calculations involving tanks, taps, and time. In a small village in southern Italy, a retired schoolteacher managed the town’s water tank during the summer months. Without sensors or timers, he used his notebook to track how fast the tank filled and how long it took to drain. One summer, a slow leak caused daily shortages, and he figured it out by estimating how many litres vanished overnight. His observations helped the town avoid a bigger problem. These water tank math problems aren’t just classroom puzzles, they come from real life situations where a bit of logic makes a difference. Take the quiz and see how well you’d handle similar scenarios.

Water Flow

A tank of capacity 800 liters is filled at the rate of 40 liters per minute. How long will it take to fill the tank completely?

If water flows into a tank at 12 liters per minute and out of it at 5 liters per minute, what is the net increase in 30 minutes?

A tank is 3/5 full. After adding 84 liters, it becomes 4/5 full. What is the total capacity?

An overhead tank can store 2000 liters. If the inflow pipe fills at 60 lits/min and is open for 15 minutes, how much more is needed to fill the tank?

A 1600-liter tank is leaking at 4 liters per hour. How many hours before it becomes half full, starting full?

A tank contains 600 liters. If one tap fills at 15 lit/min and another empties at 5 lit/min, in how many minutes will the tank get filled if both are open?

Two tanks A of capacity 400 lit and B of capacity 600 lits are filled up at 10 lits/min starting at the same time. How many more minutes does B require to be filled compared to A?

An overhead reservoir overflows if filled for more than 30 min at 50 liters per minute. What is the tank capacity?

A 500 lits tank loses 2 liters per minute due to a leak. How much is left after 3 hours?
