A good idea Jeff,

... for flowrates in a (packed)bed:

Vs =  Superficial velocity;  Vs = Q/A  where Q is the volumetric flow 
rate of the fluidum
                                     and A is the cross-sectional 
area of the bed
Vs is in m/s if Q is in m3/s and A is in m2

And for a good explanation about " Superficial Velocity " in gasifiing Stoves,
some dude called Tom B. Reed  ;-)  and his fellow's wrote in 1999 a 
nice 8 page PDF titled :
" SUPERFICIAL VELOCITY - THE KEY TO DOWNDRAFT GASIFICATION "
maybe you can find it on the Stoves pages or else here :
www.woodgas.com/Superficial%20Velocity.pdf

no need to reinvent the wheel.
