For t greater than 8, water continues to flow into and out of the pipe at the given rate until the pipe begins to overflow. Write, but do not solve, an equation involving one or more integrals that gives the time w when the pipe will begin to overflow. Alright, so the pipe is going to overflow, so we want to figure out that gives the time w when the pipe begins to overflow. So the pipe will begin to overflow when it crosses 50 cubic feet of water. You could say right when it hits 50 cubic feet of water, then it will begin to overflow. So we can figure out at what time does the pipe have 50 cubic feet of water in it. And so we could just say, well, w of this time, so I used uppercase w as my function for how much water is in the pipe, so capital w of lowercase w is going to be equal to 50.
