Influence of Flow Development Time on the Residence Time Distribution and Flow Pattern in a Scale Model of a Water Treatment Plant Clearwell
Bibliographic record
Abstract
This paper presents results of scale model testing of. the Glenmore Water Treatment Plant NE Clearwell in Calgary, Alberta, Canada. This clearwell has a perforated baffle wall at its inlet, a 4-pass serpentine system, and a weir at the outlet. The model was operated based on Froude similarity and had a scale of 1:19. Tracer studies and flow visualization were carried out for three flow rates. From the residence time distribution developed from the tracer tests, it was seen the baffle factor and Morril Dispersion index were affected by the time between when the flow in the model and tracer test was initiated. It took approximately 10 h of flow development time for the results to reach steady-state values for the minimum flow rate. At higher flows, the baffle factor was not as strongly affected by flow development time, however the Morril Dispersion index better matched prototype values at longer times.

How this classification was reachedexpand
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.
