We've all seen the room volume/air flow calculation* and, hopefully, we've all realised that it's next to useless for controlling temperature when high-Wattage equipment is used in small spaces.

To address that, I made a table which shows how much air flow is required to maintain a given temperature rise above ambient.

It's calculated using the basic heat transfer/dissipation equation, which is a standard method for estimating the cooling requirements of hot things in small enclosures (it's often used in relation to electronic devices, for instance).

I hope it's useful



*The room-volume method is derived from calculations used for building ventilation. For those who don't know it, it's 20 x room_volume per hour.

Thank you very much for this, it has shown my mate i am telling the truth and he knows fuck all!!!

I don't know if it is just me or whether this is happening for all the members, but I am unable to see what I feel should be a photo, table or graph, what i do see is "airflow-temperature.png". When I click on it I get a pop up window with a rotating cog (a bit like when youtube is buffering only it never completes and i end up cancelling it after a few minutes. This information would be very helpful to me at the moment.
