Why is the production capacity of a settler related to the settling velocity and settling area, but not to the settling height?

Hehe, Lao Yu got every daily question right – and there’s still such a question? Based on experience, if you consider that vacuum cleaners are designed to be flat, it makes sense that this is the case; sedimentation is related only to the sedimentation rate and area, and not to height. Theoretically, it’s a trajectory of projectile motion. Think about it: particles enter a sedimentation chamber horizontally, with a flow rate of Q. Here, we assume the chamber is rectangular in shape (with length, width, and height being L, W, and H respectively); the sedimentation area is A = LW, and the sedimentation height is H. From a horizontal perspective, the time taken is t1 = AH/Q. From a vertical perspective, t2 = H/u, where u is the sedimentation velocity. Since t1 = t2, it follows that Q = AU. Therefore, the sedimentation capacity Q depends only on the sedimentation area and the sedimentation velocity, right? It has nothing to do with height~~

As a layperson, it’s okay to ask questions, right? It’s fine to ask if you have any doubts – that’s what good forum users do. Your answers are very good and clear; the forum moderator even gave you high scores. I won’t give such high scores, but I hope all the moderators in the Craft section are as enthusiastic as you are --------------------------------------------------------

This might give rise to another question: what is the purpose of a settler, and what is its optimal length-to-diameter ratio?

Well, this is the same explanation as what I read in books

Why not go on talking?

You can post a thread to continue this question, and the moderators will give you a reward in wealth

Well, I haven’t mastered this part well, and it’s not necessary at the moment; I’ll review the books first and then discuss it with everyone.

None of them study chemical engineering, so they don’t understand it
