Flow ratio
flow_ratio
Operating flow divided by best efficiency point flow
Scores if within ±3% of the reference value.
Checks pump operating flow against explicit preferred and allowable operating range ratios relative to best efficiency point flow. The template reports flow ratio, POR margins, and numeric POR/AOR flags.
with-tool: The model is given an executable Python calculator script.
Standards
One template produces many comparable benchmark tasks while keeping the scoring contract fixed.
01
The reusable contract shown on this page.
02
An archetype and site context are sampled.
03
Inputs may be hidden at harder tiers.
04
The model responds with the declared outputs.
Inputs the model receives, and the outputs it is scored on.
6 inputs
Included directly in every task prompt.

5 outputs
flow_ratio
Operating flow divided by best efficiency point flow
Scores if within ±3% of the reference value.
por_margin_low
Margin above lower preferred operating range limit
Scores if within ±3% of the reference value.
por_margin_high
Margin below upper preferred operating range limit
Scores if within ±3% of the reference value.
within_por
Numeric flag where 1 means operating flow is inside POR
Scores if within ±1% of the reference value.
within_aor
Numeric flag where 1 means operating flow is inside AOR
Scores if within ±1% of the reference value.
Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.
For this template, difficulty scales through parameter and scenario ranges rather than hidden information.
The exact instruction and parameter contract used to generate this task, pinned to the published library source.
