Example Problem 1

Water is added to an empty 1100-L tank at a rate of 85 L/min. After 10 min, a valve opens and water flows out at a rate of 0.20V L/min. That is, the flow out is proportional to the height of water in the tank (and thus to the volume of water). Plot the volume of water in the tank as a function of time.
