Abstract
Abstract Experiments were conducted using a 100 mm diameter pipe loop to investigate the deposition velocity (V c ) of settling slurries in inclined pipe flows up to 20° (36.4 %). Slurries which comprised silica sand or gravel (0.1–8 mm) and water were tested at solids concentrations between 6–40 % by volume (0.06–0.4 L/L). For the fine (d ∼0.1 mm) and intermediate solids (d ∼0.19 mm, 0.3 mm), increases in V c with pipe inclination were marginal. For the coarsest solids (2 and 8 mm gravel), the deposition velocity increased significantly with pipe inclination. A comparison is made with the results of Wilson and Tse. The effect of inclination is correlated with the efficiency of turbulent suspension of the particles.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
