On the Pressure Drop and Clogging Limit in the Horizontal Pneumatic Conveyance Pipe

抄録

By using the theoretical formula and the empirical one which one of the authors has published, the pressure drop and the clogging limit in a horizontal pneumatic conveyance pipe were calculated for several conditions and the results were compared with many experimental results. For six other kinds of formulas on pressure drop and clogging limit which have been published by the other authors, similar calculations were accomplished. Consequently, it has been concluded that S. Sugwara and S. Kikkawa's formula is the most excellent from every point of view followed by E. Muschelknautz's formula.
