OPERATING RANGES OF VACUUM PROCESSES
Most of the principal industrial processes that necessitate combinations of air, other gases, and water vapor, as shown
the use of subatmospheric pressures are listed here, to- under the three headings A, B, and C. The charts on this
gether with the typical pressure range for each one. The page and the preceding one were compiled by J. F. Plum·
