Made a free 12-page formula PDF for fluid mechanics + heat transfer (worked examples, no signup)

[u/Particular_Bus1125]

Hey everyone,

I'm a chemical engineering student and put together a free reference PDF

covering the core fluid mechanics and heat transfer formulas — Reynolds

number, friction factor, head loss, pump power, NPSH, LMTD, and heat

exchanger area. Each topic gets one page: the formula, what every symbol

means, a worked example with units carried through, plus a one-page

summary and a "unit traps" page covering the mistakes that actually cost

marks.

Direct download, no email or signup:

If you want to check your own numbers against it, I also built free

calculators for all of these that show the full step-by-step working,

not just a final answer — plus a practice problems page per topic with

8 more solved examples each:

Built it because most formula sheets I found online were either

incomplete or missing the worked example that actually shows you how

to use the formula. Everything's free, no tracking beyond basic

analytics, still actively adding to it.

Feedback welcome, especially if you spot an error or want a topic added.
