Blower Process Energy Acoustic Package

Calculates source-bound blower process and acoustic metrics from a deterministic SSC-06 task-owned source pack. The template combines oxygen demand, required airflow, blower shaft power, motor input and margin, receiver sound level, criterion margin, and an overall synthetic pass score.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

Scenario archetypes

Each generated task is drawn from one of these realistic scenario bands.

Site contexts ground each scenario in a real locale the model can use to infer hidden values.
