  1. ok i think we are getting away from what i need...another example if you have a leaf blower that creates 300 cfm what changes if you increase the pipe size it flows thru??? pressure volume air speed...etc
  2. well how does pressure relate to all this
  3. thanks for your help i think i got it ok so i believe i got this right for a 1.5" pipe flowing 500cfm, velocity would be 463 mph and thru a 3" pipe 115.75 mph right?
  4. where does 1/12 come from
  5. so given the formula q=av solving for v and converting to mph i get only 3mph this cannot be right
  6. so the cfm would be the same no matter what size the pipe?
  7. yeah that was way over my head... ok i think i got everything figured out but what is the pneumatic length and that doesnt really help me with change in cfm and velocity of the air
  8. i have a constant source that produces 500CFM out of a 1.5 pipe and need to expand to 2.5"pipe. i need to know how to calculate the amount of pressure dropped and or velocity.
  9. say i have 500 cfm flowing thru 2" pipe and i have an adapter to 3" pipe will that change the cfm or velocity or both and what equation(s) would i use to calculate the pipe diameter change?
