Thanks for that Andy, [I] have managed to do this, but for small low density particles, this doesn't work. I think I need to introduce drag, and terminal velocity, as I know the material l;ess than 5 mm and density of less than 100 kg/m3 with be carried off in the air stream. How do i...

(I'm new to the forum and think I may have posted this in the wrong area - have just copied and posted here so hope this is correct) Its a while since I've done any motion calcs so I'm after some guidance. I am vertically dropping a range of materials (size 8-20 mm) into a horizontal air...

Its a while since I've done any motion calcs so I'm after some guidance. I am vertically dropping a range of materials (size 8-20 mm) into a horizontal air stream in a pipe (pipe diammeter d , ~0.3m) The horizontal air velocity in the pipe is 10 m/s The particle bulk density ranges from...
