Reading Wiki is somtimes like reading Windoze XP tuneup sites - right and wrong blended into an indistinguable mass.

Ahh a prime example right there, because GB introduced all this Chewbacca gear to distract everyone else, and I never said lights don't use energy. :) (Though some lights may be magic if they are fairies) Nev..

It's one of those words that becomes the jargon for a particular field. Laminar flow became a focus of terminology when in Young during the drying season for Prunus domestica. The original drying tunnels had been built by soldiers returning from WWII. They were inefficient and becoming uneconomical and as a result, these a range of other fruits that are dried similarly could be imported cheaper. To keep the market viable, consider value adding and to determine the kinetics, physical and chemical changes the drying tunnels were examined. Laminar flow was a big buzz word then! Hammo |
