Packed Bed Consisting of Different Sizes of Glass Spheres

The aim of this research is to study the packed bed using theoretical methods and experiments. Five types of glass spheres were used which represent the packed bed with diameters of(d972, d2 = 10.164, d3= 14.772, d = 20.614,d54 = 25.448 mm).The theoretical methods which were given by latif consist of calculating the pore diameter, mean pore diameter and the probability due to (number,length, area, and volume). The results obtained using computer program and these results showed that the probability of finding pore size in any packed bed is different for each distributions. An experimental apparatus was built,
which consists of glass cylinder in which five types of spheres put in, sieve, and impurities passed through the packed bed. Results obtained from the experimental work showed that the percent output of impurities decreased with the increase of the number of layers; and also decreased with increase of size of impurities for each value of number percent of spheres. Experimental results are related with
theoretical results in order to find the relation between mean pore diameter and percent output of impurities for each bed, the increase in size of spheres lead to increase the mean pore diameter
