Need to solve mathematical model

[AmmaraBaig]

Hi,

I have an excel spreadsheet that can predict the air composition of a room based on the room size, number of occupants, leakage rate inside the room and gas infiltration. I would like to develop this model one stage further.

Please see the attached spreadsheet where in red text I have mentioned needs.

Waiting of your reply.

Sorry, but the purpose of this website is not to program spreadsheets for others. If you have an engineering-related question, that's fine, but what you appear to need is someone who wishes to write equations in spreadsheet form.
