HIGH AIRFLOW OR HIGH STATIC PRESSURE, WICH USE ? (AXIAL AND CENTRIFUGAL FANS)
Hi, I have a question about fans.
I need to use a fan for my carreer final proyect and im not sure what kind of fan use here. ( i have doubts about wich fan to use, high airflow fans or high static pressure fans).
My project consist in levitate a ball(or any aerodynamic object) by air , the ball will be in a tube and the fan will woks with out dust or big particles( clear air ).
There are fans that priorize air flow vs static pressure , and my question is wich type of fan i need to use here . ( I can use axial fans of centrifugal fans).
The goal here is move a ""heavy"" object (the ball) so wich kind of fan will use you ?
(I know that i need to aply bernuilli equation to know the force aply to the ball(and the drag equation later), but i dont know if i need high air speed/air flow or static ourtput pressure)
Thanks and kind regards.
Calculate the terminal velocity of the ball using:
If this velocity is v m/min, and the area of cross section of the tube is A m2, then the flow rate for the fan has to be more than A x v m3/min for the ball to levitate. Use Darcy–Weisbach equation to calculate the pressure drop that the fan should develop.
