tilt_pour_rate — DRIVE scoop op

• Data kinds: scalar × scalar × scalar × scalar × scalar × scalar × scalar → table

• 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"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

:func:tilt_wedge_retained の器を角速度 ω で傾けたときの準静的な流量 `W = ρ_b B (−dA/dθ) ω` [kg/s]

(供給で決まる流量: 口の通す力より遅く傾けている限り、流量は傾ける速さで決まる)。

`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)。
