Look at table 12.12.1.2(a), 2010. The minimum density is .60 from 8ft to 20 ft. The .45 is only good to 8 ft. Unless the pile sizes are small and well spaced I think you are looking at 8-10 ft max height. The orifice size at 11.2 and above is not the most important factor. The density controls heat.

I know we can interpolate densities based on area etc... but is it okay to interpolate storage height based on density when only a single point is given in the table? We have and area/density system that is capable of 0.495/2000 using 16.8K heads. Interpolating between 0.60 for 20 ft. storage and 0.495 would allow 16'-6" max storage height of idle pallets.
