Calculation method

Calculation method

Length clearance (m)

Stored bounding rectangle=(roll length+2supportAllowance)×rolledDiameter.

Depth clearance (m)

Stored bounding rectangle=(roll length+2supportAllowance)×rolledDiameter.

Stored assembly fits rectangle (1/0)

Stored bounding rectangle=(roll length+2supportAllowance)×rolledDiameter.

Symbols and units
a
Cover/reel stored length (m)
b
Measured rolled diameter (m)
c
Support allowance each side (m)
d
Available storage length (m)
e
Available depth (m)

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

  • Calculation uses the entered values and stated mathematical model; quantities must use the labelled units. 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. Stored bounding rectangle=(roll length+2supportAllowance)×rolledDiameter.
