Narrow particle size distribution basalt pebbles of mean particle size 11. 5 mm conveyed by water in the pipe sections of different inclination were investigated on an experimental pipe loop. consisting of smooth stainless steel pipes of inner diameter D = 100 mm. Mixture flow-behaviour and particles motion along the pipe invert were studied in a pipe viewing section. https://thegreensjunglebeautyshops.shop/product-category/nail-polish-thinner/
