Supply grill selection based on FPM

I read that a target range for FPM should be around 600 to 800. Hart and Cooley recommends 700 FPM. The companies I used to work for just based it on the approximate cfm. For example, 110 cfm would be 10x6, 160 cfm would be 12x6, and 200 cfm would be 14x8 grills.



I was looking at some H&C data charts. The data seems to show that 110cfm would warrant an 8x4 grill. It would have a throw of 12 feet, however. Should the throw just be at least 5 ft? It seems like there would be excessive noise. I'm looking at the A618 side wall grills.



What A618 grills should be used for:



110 CFM

400 CFM



I don't see data for the 12x12 and 14x14 grill. Which one would be recommended for 400 cfm?
