Calculation method

Calculation method

Usable media volume (L)

Capacity=LWH/1000×(1-clearance fraction).

Package total volume (L)

Capacity=LWH/1000×(1-clearance fraction).

Unused volume or shortfall (L)

Capacity=LWH/1000×(1-clearance fraction).

Symbols and units
a
Chamber internal length (cm)
b
Chamber internal width (cm)
c
Usable media height (cm)
d
Clearance fraction
e
Media package volumes (L)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Volume capacity only; package shapes and water-flow restrictions not modelled. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Volume capacity only; package shapes and water-flow restrictions not modelled.
