DISCUSSION OF RESULTS In this experiment, there were four different packing materials: sand, glass beads, rashing rings and berl saddles. The first five runs using the sand bed, the flow rate was between 3.79*10 -6 and 1.64*10 -5 m 3 /s. And as the flow rate increased, the pressure drop increased from 1549.98 to 8220.78 Pa. A direct relationship was observed between the flowrate and ∆P/L. The friction factor decreased while the Reynold’s number increased. The error from the theoretical values varied from run to run. The same applies for the other beds as shown in the tables. The value of the shape factor was also obtained to be 1.0 for sand and glass, 0.197 for the rashing rings and 0.69 for the berl saddles. The following relations were obtained from the plots of f p vs. 1/Re: For Sand f p = 170.77/Re + 2.0872 For Glass f p = -156.3/Re + 2.0686 For Rashing Rings f p = 1104.6/Re – 1.3147 By comparing these equations from the graph with Ergun equation, I found these equations are close to the Ergun equation except for the Rashing Rings. Also, I
