hm
<whitequark>
i'm currently being bad at math
<whitequark>
so let's consider a room with a human in it
<whitequark>
if the human exhales x mg/s of CO₂, and the concentration is steady state, by definition it means that x mg/s of CO₂ leave the room
<whitequark>
but in this case, if the dominant mechanism was convection, wouldn't any steady state concentration be just 410 ppm?
<whitequark>

i feel like i'm missing something obvious

whitequark: why 410
<whitequark>
ambient
<egg|zzz|egg>
ah
<egg|zzz|egg>
whitequark: so gas eggschanges with the outside are going to make the CO₂ concentration tend towards 410 ppm (so if it's higher, say 420 ppm, it's going to become lower over time); but it won't do so instantaneously (and the closer the concentrations the smaller the net CO₂ mass flow)
<egg|zzz|egg>
so for any mass flow from the cat inside, there is some concentration higher than 410 ppm at which the inside will settle
<whitequark>
hmm
<whitequark>
oh
<whitequark>
interesting

whitequark: consider a well-mixed room filled with α of CO₂, 1-α something else, and outside β CO₂, 1-β something else; if you have 1 l/s coming in from outside and 1 l/s going out from inside, you have a net flow outwards of α-β l/s of CO₂

(and thus that's the steady state if the cat in that well-mixed room is producing α-β l/s of CO₂)
