| Abstract: | Pressure drop dependences on gas and solid flow rates and solid concentrations for a vertical pipe section and for a conical—cylindrical—conical chamber have been determined. Equations for a particle—wall friction factor have been obtained. Values of particle—wall friction factor for a vertical pipe section are in reasonable agreement with literature data. For a conical—cylindrical—conial chamber friction factors can be both positive and negative. |
