    Hello

    I got a tank that contains 9000 liter of water. Flow rate of water leaving the tank is 1900 liter/hour and flow rate of water entering the tank is 1800 liter/hour.

    How do I know the elapsed time it takes for the water in the tank to remain 1000 liter?:bawl:

    The net flow from the tank is 1900-1800=100 liter/hour.
    8000 liters needs to go for 1000 liters to remain (9000-1000).
    8000/100=80 hours.
