   I will look into this.   
   I can start with using a "wet&dry" workshop vac. to start "concept"   
   experiments.  Mine you can connect the hose to the "blow" side, which   
   should help.

   You can measure the pressure rise or drop related to air flow with a clear   
   tube containing colored water. If sloped at six degrees the height of water   
   is amplified 10x. As long as your setup gives repeatable numbers it needn't   
   be accurate, you can compare readings to results.
