Abstract: An equation, derived from experimental data, was developed to describe the pressure-drop-flow relationship in fixed beds of small, irregularly shaped particles. Within test limits the calculated and measured values agreed within 6 percent. Because this study was undertaken to solve a particular problem, it is specialized and the range of parameters is fairly restrictive. All experimental runs were made with beds of particles with an average particle diameter ranging from 4.8 to 45 ..mu..m and hydrogen flow rates of 3.11 x 10/sup -3/ to 1.52 x 10/sup -1/ SCFM/in./sup 2/ With one exception the bed material was deactivated FeTi hydride or unhydrided FeTi alloy; one run was made with SiC powder, which has approximately the same particle shape and surface characteristics as FeTi. The pressure-drop data were used in the design of a hydride reservoir to determine the spacing of porous-metal tubes which serve as particle-barrier filters in the bed.
