heap_volume_cone — DRIVE `granular` op

• Data kinds: scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.heap_volume_cone(R: 'float | None' = None, H: 'float | None' = None, phi_deg: 'float | None' = None) -> 'dict' (to call the implementation directly, import granular; granular.heap_volume_cone(R: 'float | None' = None, H: 'float | None' = None, phi_deg: 'float | None' = None) -> 'dict'; from the registry, opsdrive.get("heap_volume_cone"))

Usage

Closed form for a conical heap — given exactly 2 of R, H, phi_deg, returns the remaining one and the volume.

V = (π/3) R² H、H = R tan φ。返り: R, H, phi_deg, V [m³]、A(底面積 πR²)。Raises ValueError: 与えた数が 2 つでない、または ≤ 0 / 非有限 / 角が (0, 90) の外。3 つ全部渡されたときも拒否する(矛盾した 3 つ組を黙って片方で上書きしない)。
