Feels aimed at people who’ve already tripped over the obvious gaps and want names for them. The BEP vs DEP boundary in Section 2.4, especially the battery limits checklist tied to the sample P&ID, stuck; that’s the kind of thing that bites you in oilgas infra when arch docs meet CI handoffs. It’s mostly clear, though I wasn’t sold on the brief pass over IFC vs IFD revisions. I’ve moved from barely adequate to actually competent, which helps in prod.

Coming from software, this course reframed an old control problem the way refactoring a legacy service does: same constraints, clearer mental model. The walk through the ISA sizing equation, especially the Cv vs Kv example with water at 60°F, stuck because it mirrored how I sanity-check RPS assumptions in prod before a PR lands. I liked the section on flashing vs cavitation; the pressure drop chart felt like reading infra limits instead of hand-wavy arch talk, and it clicked fast. As a beginner track it mostly lands, though I wasn't sold on how briefly valve trim selection was handled; a few more edge cases would help folks crossing over from chemicalpharmaceutical or energyutilities. The pacing works for between-meeting study, and the exercises felt closer to CI checks than homework. I've already reused the sizing worksheet like a repo snippet, which is saying something.

Needed material that wouldn’t fall apart under a PR-level sanity check, and this mostly held. The LMTD vs ε-NTU section, especially the shell-and-tube example where fouling factors changed sizing, stuck with me and maps well to how I think about legacy arch versus modern constraints. It connects old plant math to how I reason about infra tradeoffs in prod, even if the plate exchanger coverage felt light. still, it trimmed a lot of mental tech debt I’d been carrying from chemicalpharmaceutical work.

The scenarios felt close to real shop-floor calls, not toy problems, which helped bridge classroom math to prod constraints. Chapter 3’s LMTD vs ε‑NTU walk-through, especially the fouling factor table for a shell‑and‑tube case, stuck with me; it’s the kind of calc I’ve already sanity-checked in a PR comment for a chemicalpharmaceutical design note. mostly worked for beginner/intermediate, though I wasn’t sold on how lightly startup transients were treated. Good enough that I’ve gone back twice to re-read those sections.
