Good day to all! I have a question : We have a flowing fluid ( liquid ) with known pressure, flow in the pipe ( pump is pumping it). There are some spherical microparticles in the liquid, let's say 10-15 microns. I want to create force to stop them moving! Will the pressure force be in the form of F = pA ( p - pressure of the fluid A - area of the particles ). ??? Sorry, if the question is too easy or too fool)))) It is needed for my project.
