Tubing Equations

[Jordan_6565]

Does anyone know any equations that can be used to figure out how far matter can be blown through a section piece of tubing? I need to figure out how far I can blow fish food pellets through a piece of tubing and I know that the fact that I am blowing pellets instead of large solid objects or liquid will complicate things. Any help would be greatly appreciated!

Calculate the pressure, calculate the section, and you have the driving force F. You can then calculate the exist speed from the length of the tube. The trajectory of your object will be a parabola and there are formulas for calculating under what angle you need to launch for maximum distance (www.cbu.edu/~jmonzyk/Phys150/ProjMot.ppt) (45°) and what this maximum distance will be.
