Pressure drop correlation was developed for saltation flow of a concentrated settling suspension in a horizontal pipe. The important variables of the system are the densimetric Froude number and the pressure drop of the equivalent pure-fluid flow, which take the net fluid section into account. On the basis of the Kelvin-Helmholtz instability of stratified pipe flow, these variables are approximately expressed by independent variables of the system so as to make a prior prediction of the pressure drop. From experimental pressure drops, the validity of assumptions was confirmed and the diameter-ratio dependence was determined experimentally. The equation was tested for water and other carriers. Some methods for pressure-loss reduction at fixed values of drag coefficient are discussed.
