Thanks for the formula, John. But I should point out that at higher densities, depending on air as a thermal ballast during data center cooling outages doesn't scale, since racks just start to re-breathe their exhausts. I saw an interesting CFD simulation showing that in an environment built out to 400W/sq ft, a rack will overheat in 10 seconds.
