You have a pond with decorative fish in your back yard. The pond holds 800 gallons of water. Once a week you pour fresh water into the pond at the rate of 100 gallons per hour. The pond is filled to the brim, and so as you pour water into the tank water flows out at the same rate. There is a pump in the pond that keeps the water perfectly mixed.
