The initial pressure (velocity) of the air.
How much cooling is needed per rack. (Is it the same for all racks, or do some racks need more cooling than others?)
The arrangement of solid and perforated tiles (in different perforation percentages) to deliver air at the correct pressure to each rack.
The following figure shows an example of how pressure (in this case, water) diminishes as it is systematically leaked. The example shows a hose with three identically sized holes. The greatest amount of water pressure is leaked from the first hole. The pressure from the second hole is ...
