Batch Storage (for Bulk Solids): Volumes Tab

Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable	Default Value	Range

○ Max Allowable Working / Vessel Volume (%) The maximum allowable volume of vessel contents expressed as percentage of the volume of the vessel.	90.0	(0,100)
○ Min Allowable Working / Vessel Volume (%) The minimum allowable volume of vessel contents expressed as percentage of the volume of the vessel.	15.0	(0,100)
● Initial Working / Vessel Volume (%) The volume of vessel contents before the operation, expressed as percentage of the volume of the vessel.	90.0	(0,100)
● Final Working / Vessel Volume (%) The volume of vessel contents after the operation expressed as percentage of the volume of the vessel.	0.0	(0,100)
● Initial Working Volume The volume of vessel contents before the operation.	0.0	Positive
● Final Working Volume The volume of vessel contents after the operation.	0.0	Positive
○ Bulk Density (g/L) The bulk density of the solids material.	850.0	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

Note this tab is being used by several operations, including Batch Storage (for Bulk Solids), Mixing & Drying, Granulation, etc.

The bulk density, specified by the user, is used to calculate the bulk volume of the equipment contents.

In Design Mode, the Maximum Allowable (%) value is used for sizing the equipment. If multiple operations in the same procedure recommend sizing values, the procedure selects the maximum.

In Rating mode, the Maximum Allowable (%) acts as a constraint that generates a warning when it is violated. The Minimum Allowable (%) value always acts as a constraint.
