.88 what/hr?
I think It's number of exchanges of air aka I
is this like an HVAC class? i never had to do this stuff.
from what's here, doesn't it depend on how efficient the exchange is? like, who cares how many exchanges there are, but how good is the filter?
so if i assume it's .88% efficient i get 1.3
but i know nothing about this.
its called physical principles of environmental science. its all about mass and energy balances
it was weird because normally we use K and we know the decay rate and not the air exchange rate but im pretty sure they are the same thing because they both account for a loss per time
i set up a transient problem with different boundaries and got 1.04 then i solved it steady state and got 1.4 so i know i had to be at least close to the answer
i think the actual answer involves calculus which i hopefully got right on the test lmao
