Space velocity specific gravity

Soil-bearing pressures, 99-100 Soldering, 448 Solid-waste disposal, 88-90 Space velocity, definition of 728 Specific gravities of liquids, 882 of solids, 883... 

Because of slow kinetics, space velocities must allow residence times of 20 to 120 min and are therefore around two to dtree volumes per volume per hour, in two or three in-line columns, two to three meters high. This set up allows bed permutation and maximum saturation in the first column (bed specific gravity of 0.42 to 0.46).
