) is already very high (like in boiling water), adding fins actually hinders the process. Fins are best used when the fluid is a gas (like air) because air is a terrible heat conductor. Quick Chapter 3 Cheat Sheet Key Formula Why it matters Basics of building insulation. Cylinder Pipes, water heaters, and steam lines. Contact Resistance Why two metals touching aren't "perfectly" connected.
Fin analysis is notoriously algebra-heavy. You must calculate fin efficiency, effectiveness, and temperature distribution for infinitely long fins, adiabatic tips, and convective tips. Problem 3-120 to 3-140 in the 5th edition are classics. ) is already very high (like in boiling
$\dotQ_conv=150-41.9-0=108.1W$
However, I can guide you on how to approach finding solutions or understanding the concepts in Chapter 3 of the 5th edition of "Heat and Mass Transfer" by Yunus Cengel. Cylinder Pipes, water heaters, and steam lines
