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.

Module 4 dragged a bit, and the homework assumes you’re already fluent in Excel Solver. That aside, the selection logic is what pulled me in: the decision trees for choosing shell-and-tube vs plate in Chapter 2, especially the LMTD vs ε‑NTU fork with the fouling factor example at minute ~18. As someone who thinks in arch diagrams and failure modes, mapping thermal constraints the way we map infra tradeoffs clicked. The counterflow vs parallel-flow section tied pressure drop back to maintenance in a way I’ve actually seen in chemicalpharmaceutical plants. it wasn’t fluffy, and it didn’t pretend everyone’s starting from zero. I’ve already bookmarked the pinch-temperature walkthrough for quick reference between meetings.

Section 3's shell-and-tube LMTD worked example (120→80°C, 2-pass) stuck; the step where fouling factor bumps area made the math click, it's easy to map to a prod calc. Mostly helpful, but I wasn't sold on the brief NTU coverage—wished there was more obs on sizing tradeoffs for chemicalpharmaceutical service.
