• Call: import fullseye as fs; fs.ledger.tilt_pour_rate(theta_deg: 'float', omega_deg_s: 'float', phi_deg: 'float', L: 'float', h0: 'float', B: 'float', bulk_density: 'float') -> 'dict' (to call the implementation directly, import scoop; scoop.tilt_pour_rate(theta_deg: 'float', omega_deg_s: 'float', phi_deg: 'float', L: 'float', h0: 'float', B: 'float', bulk_density: 'float') -> 'dict'; from the registry, opsdrive.get("tilt_pour_rate"))
Quasi-static flow rate W = ρ_b B (−dA/dθ) ω [kg/s] when the container of tilt_wedge_retained is tilted at angular velocity ω (supply-limited flow: as long as it is tilted more slowly than the mouth can pass, the flow rate is set by the tilting speed).
> The detailed description below is the original text — the summary and the headings are translated.
dA/dθ: 斜面が奥に届く前(x_k = h₀ / t < L)は −h₀² sec²(φ−θ) / (2 t²)、届いた後は −½ L² sec²(φ−θ) (t = tan(φ − θ))。θ = 0 では h₀² / (2 sin² φ)(前面の斜面の長さ h₀ / sin φ の楔)。
返り: rate [kg/s]、rate_area(−dA/dθ·ω [m²/s])、fraction(出た割合)、theta_back_deg。Raises ValueError: 引数の範囲(ω ≤ 0 を含む)。
