Calculation method

Calculation method

Retained clay volume (cm³)

pi(outer radius²×outer height−inner radius²×cavity depth).

Starting clay mass (kg)

Retained volume×density×(1+trim allowance/100)/1000.

Assumptions & limits

Assumptions & limits

  • Target inner-outer geometry, trimming allowance, density. Returns Clay mass estimate. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Green outer cylinder radius (cm): minimum 1e-12, maximum 1000000000000.0. Green outer height (cm): minimum 1e-12, maximum 1000000000000.0. Green inner radius (cm): minimum 1e-12, maximum 1000000000000.0. Inner cavity depth (cm): minimum 1e-12, maximum 1000000000000.0. Measured wet density (g/cm³): minimum 1e-12, maximum 1000000000000.0. Additional trimming mass allowance (%): minimum 0, maximum 1000.
