The optimum operating velocity is between 50 and 80% flood for all packings, which deviates from the experience with distillation column design, usually optimized at 70–90% flood. Someone smarter than me can probably elaborate further. The mixing area is kind of narrow at 9' 9", so there is also a bit of a width restriction to go around the back of the desk (between the desk and the wall once the absorbers are mounted). Soft ground is porous and absorbs sound waves.
