'Brink DepthDischarge' Relationship for SpatiallyVaried Flows in Pipes
Bibliographic record
Abstract
In view of the selfcalibrating feature, the brink depth generated at the entrance to a freelydischarging drop structure in a prismatic open channel is widely used for estimating channel discharge. Laboratory investigations on this subject have been performed for both subcritical and supercritical flows in differentshaped prismatic channels. However, these studies have examined the brink depthdischarge relationship for constant channel flow conditions only. This research investigates the brink depthdischarge relationship for circular pipes carrying subcritical spatiallyvaried flows (SVF) with discharge increasing in the flow direction. Results indicate that for this type of SVF the brink ratio (BR) is: (i) closer to unity than that for constant discharge, and (ii) offers reasonable accuracy in regards to estimating SVF in a circular pipe section.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
