Pump Affinity Retrofit Energy Package

Calculates source-bound pump retrofit metrics from a deterministic SSC-06 task-owned source pack. The template combines pump affinity-law flow/head/power changes, annual energy and cost savings, NPSH margin, motor 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.
