A tank that currently contains 2500 gallons of oil empties at a rate of 25 gallons per minute. The capacity of this tank is 3000 gallons. How many gallons are currently in the tank? \[ 2500 \text { gallons } \] How fast does the tank empty? - 25 per minute

Did you know that the concept of tanks and fluid dynamics dates back to ancient civilizations? The Egyptians, for instance, built incredible irrigation systems using basic tank-like structures to channel water from the Nile. Fast forward to today, understanding how tanks empty helps engineers design everything from oil refineries to swimming pools, ensuring effective management of resources. In real-world applications, such knowledge is crucial for industries relying on fluid management—like oil, water, or chemicals. For instance, if this tank empties at 25 gallons per minute, you can easily calculate how long before it becomes empty. Just divide the current amount (2500 gallons) by the drainage rate (25 gallons/minute) to find that it will take 100 minutes to fully empty! Keep that in mind next time you’re checking out tanks!
