See how early would look in a straight line but construction has strong point dep do will make it lower and enough speed to 1100 micron particle that does not trap will start flowing.
That beginning to look like a straight line, but near the construction has made the dep will degrade, and in the 1100 micron particle trap that is starting to flow out.
That the first will look straight but when approaching the point construction has strong dep shall make the speed decreased, and when the 1100 micron Particle not trap will start flowing out
