When doing the calculations required in Sec. 174.065--
(a) The permeability of a floodable space, other than a machinery space, must be as listed in Table 174.090; and
(b) Calculations in which a machinery space is treated as a floodable space must be based on an assumed machinery space permeability of 85%, unless the use of an assumed permeability of less than 85% is justified in detail.
95 or 0.1Other liquid tanks.........................
95 or 0.2------------------------------------------------------------------------1 Whichever results in the more disabling condition.2 If tanks are partially filled, the permeability must be determined
from the actual density and amount of liquid carried.
