Abstract
Throttling water pressure transforms useful mechanical energy into heat via a thermodynamically irreversible process. Alternatively, energy recovery hydro turbines or pumps as turbines can be used to generate power from excess water pressure. This study investigates the influence of water system and turbine characteristics on the economic feasibility of energy recovery turbines and develops general design principles that benefit infrastructure planners who may consider energy recovery within water systems. Results indicate economic feasibility is predictably influenced by a variety of factors. For instance, service reservoirs can decrease the levelized cost of electricity in the range of 10% and provide some generation dispatchability. Smaller turbines decrease the levelized cost of electricity in the range of 30%, but sacrifices energy recovery potential. Although challenges exist, energy recovery turbines can be an economical, flexible, and renewable option for controlling pressure and deserve serious consideration within some water supply systems.

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
