Short Communication Prediction of pressure drop for a conical fixed bed of spherical particles in gas-solid systems

The object of this work was to develop an equation to predict the pressure drop in coni-cal beds of spherical particles. Work reported earlier is limited to a single cone angle in liquid-solid systems, whereas in the present study cone angles of 10°, 30°, 45 ° and 60° were used to predict the pressure drop for fixed beds. Air was used as the fluid medium and the bed consisted of spherical glass parti-cles of various sizes. The constants C1 and C2 were determined and were used to calculate pressure drop values. Experimental and theo-retical values of pressure drop were compared and the mean and the standard deviation were calculated
