WebAs the flow rate increases, the tank fills up faster and faster: Integration: With a flow rate of 2x, the tank volume increases by x2. Derivative: If the tank volume increases by x2, then the flow rate must be 2x. We can write it down this way: The integral of the flow rate 2x tells us the volume of water: ∫2x dx = x2 + C.
