Calculation method

Calculation method

Substrate bulk volume (L)

Linear front-back slope volume=L W (front+back)/2000.

Nominal purchase mass (kg)

Linear front-back slope volume=L W (front+back)/2000.

Symbols and units

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. Linear front-back slope volume=L W (front+back)/2000.
