Hi guys,
I intend to model the distribution of CO2 in a room. I have written the governing equation for CO2 concentration, but I have the CO2 production rate in the room in units of L/s. How can I convert this production rate to ppm/s? |

Divide by the volume over which the production occurs (the entire room?) and then multiply by 1 million

Thank you for responding.
The production of CO2 occurs through the breathing of individuals present in a room. Shouldn't we divide the rate of CO2 production by the exhaled air rate of individuals and multiply it by one million to obtain the ppm (parts per million) value? |

well that would certainly depend on whether your rate in L/s is for one person or one thousand. When you say you have the rate, I have to assume that you actually have the rate.

The concentration of CO2 is not dependent on the number of individuals. If we divide the CO2 production rate in L/s by the exhaled air rate in L/s, whether it is for one person or one thousand people, the CO2 production rate will remain constant in ppm/s (parts per million per second).
Now, my question is how to convert the CO2 production rate from L/s to ppm/s, regardless of whether there is one person or one thousand people. |
