And then I have this section right over here in green. So what is the area of this entire thing? Well, the area right over here, we have 20 gallons per minute. So 20, oh sorry, not 20 gallons per minute, 20 minutes times two gallons per minute, two gallons per minute times 1 1⁄2. Times 1 1⁄2 gives us the area under this triangle. So that is going to be 20 gallons. 20 gallons, we see that the units work out nicely.
