How do you calculate the flow rate of water into a tank?

Back

To calculate the flow rate, divide the total amount of water by the time it took to fill the tank.

Front

If a tank has 648 gallons after 36 minutes, what is the flow rate?

Back

Flow rate = 648 gallons ÷ 36 minutes = 18 gallons per minute.
