CO² concentration over time
CO² concentration over time
(OP)
Hi all,
I don't know how to calculate following problem:
Problem:
I have a room with a certain concentration of CO2. There is a leak which causes the concentration to fall over time.
Known:
CO2 concentration start = 43.0%
CO2 concentration after 10 minutes = 22.2%
CO2 concentration air outdoors = 0.04%
Asked:
What should the initial CO² concentration be to have the minimal CO2 concentration after 10 minutes = 38% ?
Any help?
*edit*

A common engineering assumption would be that dC/dT is constant and that C(t) is linear and determine dC/dT from 2 points where the change in C and the change in time is known, and you're doing 7th or 8th grade math in the US, or 5th grade math in many other countries. That's as simple as it gets. Beyond that responsibility for passing on this, getting this right or wrong is yours.
