Capacity tables are based on 1.0 specic gravity
air. If other blanketing gas is used, convert the
tabular values as follows. For blanketing (pad) gases
other than air, multiply the given air ow rate by
the correction factors in Table 6. For gases of other
specic gravities, divide the given air ow rate by the
square root of the appropriate specic gravity.
