Velocity profiles in verticle mills,Our company is a large-scale heavy enterprise that taking heavy mining machinery manufactory as main products and integrated with scientific research, production, and marketing. We are concentrating on producing and selling machines such as jaw crusher, cone crusher, hammer crusher, ball mill, sand maker, mobile crushing plant
Begingroup due to continuity and symmetry your flow profile is the same at any vertical location hence the pressure loss per unit length is the same everywhere except that in your case of a vertical pipe you need to add the effect of gravity which i believe you have separately accounted for already
