Mean  expected  flow  region  –  between  5.5  and  8  m/s

However,  not  accurate  simulaFon.  Assumes  atmospheric  pressure  at  inlet  and  expected  flow  rate  at  output    does  not  account  for  pressure  losses  elsewhere  in  hookah,  so  assumes  that  they  occur  only  in  flowmeter.  Consequently,  simulaFon  overesFmates  dP

ExponenFal  fit  used  because  dP  is  funcFon  of  velocity^2  

Significantly  higher  pressure  differenFals  than  expected  –  simulaFon  results  are  much  closer  to  accurate  

Needed  new  flow  sensor  –  appears  to  work  beUer,  but  sFll  possible  to  “max  out”.  Need  to  reanalyze  what  maximum  flow  rate  is

IniFal  results  indicate  that  contaminaFon  of  the  sensor  itself  is  unlikely  to  be  a  problem,  but  flooding  of  the  pressure  lines  with  hookah  fluid  may  be.
