Process Piping Valve Control Package

Calculates source-bound process piping valve and control metrics from a deterministic SSC-11 task-owned source pack. The template combines valve Cv, pipe velocity, pressure-loss margin, control signal scaling, bend thrust, 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.

easy:
All source-pack values given for the SSC-11 process valve package
medium:
All source-pack values given for the SSC-11 process valve package
hard:
All source-pack values given for the SSC-11 process valve package
