What formula would i use to move an object with forced air pressure?

Question

I need to move empty boxes from one conveyor to another by means of forced air. The empty box activates a sensor which then releases forced air at a different location to move the box on to a different conveyor. I need to keep the box straight as it is transferred to the other conveyor.

Answer 1

The air will exert the force on the box

P=Vp
P- pressure in N/m^2
V - velocity of air in m/s
p - density in N/m^3

F= PA
F- force exerted on the box
A- effective area of the air hitting the box

Finally

F=VpA
