# Thread: Size of Hole From Rate

1. ## Size of Hole From Rate

Hello, I'm working on a calculus project and need to know whether or not this is possible and how I'd go about solving this.

Would I be able to calculate the circumfrence of a circular shaped hole in a cylinder-shaped pipe if I have the rate at which the hole ejects smoke, the rate at which the room the pipe is located in fills, and the volume of the room?

And what would the formula be to go about solving this?

Thanks.

There is no mathematical relation between "smoke" and depth of a hole. How much smoke is produced will depend upon chemical and physical properties of the drill and pipe which are not given here.

Well the smoke is just the specific portion of my problem. But it can be easily substituted for anything else like water.
