... transported into the receiver through the vertical pipe. Local concentration ( C Vl) is that which is obtained when a control body of the pipe is selected and considered. Lifting velocity is a critical velocity at which particles can be just lifted upward in the pipe. And slip velocity is the velocity...

... ABSTRACT: Some recent efforts for better understanding and prediction of upward pipe flow of Newtonian solid-liquid slurries are discussed. Experimental data are presented for slip velocity of 10 mm particles in a 150 mm pipe and for hydraulic gradient of coarse sand in a 20 mm vertical pipe...
