Measurement of the velocity of particles falling under gravity
Thread Content
I have a project to design a tube containing small particles with a diameter of 2-3 mm. Fall down along the inclined tube. Only friction and gravity are considered. The owner wants to measure the falling speed of these particles. But we can’t find the right instrument to measure speed. I was wondering if anyone has any suggestions? Or recommend a brand of gauge that can be used for measurement. ----------------------------------------------------------------------- Things got busy starting in the second half of the year, and I’m no longer acting as a moderator on the craftsmanship forum – I simply don’t have the time. I’m still sitting in the office. Wish the forum keeps getting better; I’ll keep coming back to check it out~
I think it’s possible to do this: by using the measured length of the tube and the time it takes for the particle to reach the bottom, the acceleration can be calculated, and then the velocity will be V=aT
Could a weighing device be added above or below this section of pipe? It’s just my personal opinion; I hope you won’t laugh at me.
Ask the manufacturers; there are many companies that produce instruments and sensors, such as Mettler, Honeywell, Dräger, etc. See if they have any relevant products
It’s accelerated in segments, so it’s impossible to measure accurately.
The weighing method won’t work; it involves accelerated segments, and what we’re looking for is the maximum speed.
I’ve asked already; the manufacturer is still Honeywell. . .
Even professional manufacturers can’t solve it; it’s amazing that a forum can do it. We should get more opinions from professional manufacturers as well
Is the material in a full pipe or a half pipe?
Half tube: if the character count is insufficient, more text needs to be added
Prepare 10 tubes, with each one being 100 mm shorter than the previous one; start working with the shortest one, which is 100 mm long~~~
