I'm currently building a device that will blow a ping pong ball vertically up a tube but don't know what fan I am going to need. Each fan gives a CFM flow rate but the problem is that I don't know how to calculate the required fan CFM i'll need in order to push the ball vertically. In other words I don't know how to calculate the pressure that a certain CFM fan will put on the ball in the pipe. Also the need to calculate against the force of gravity.
Ping Pong Ball Specs:
Weight= 2.7 grams
D= 40mm or 1.574 inches
SA/2 (because the air will only hit one side of the ball) = 15.558
Pipe Specs:
D= 1.75
L= between 4-10 inches
