1. The problem statement, all variables and given/known data I have an "abstract" problem. Calculate the maximum cooling capacity for forced air cooling of a room. The room contains two computers that each has a energy usage of 1 kW. v_air_in=75m^3/h v_air_out=30m^3/h 2. Relevant equations As the cooling is done by ventilation (ie. no air conditioning), I am free to use an empirical formula if I can find one, provided I can argue why it's sensible. Unfortunately I haven't found one, do you know where I can find one (eg. article link)? 3. The attempt at a solution I haven't started this part yet.
