Heat Transfer (28) - Heat transfer in internal flows in tubes examples

Correction: At 31:50, the viscosity of water at 330 K should be 489E-6 N s/m^2. The viscosity of water at 325 K is 528E-6 N s/m^2 (the entries for viscosity at 325 K and 330 K are next to each other in the thermodynamic property table). Professor Biddle accidentally wrote 528E-8, but used 528E-6 in calculating the Reynolds number.
[Time stamps will be added in the future]
Note: This Heat Transfer lecture series (recorded in Spring 2020 & Spring 2022) will eventually replace the earlier Heat Transfer series (recorded in Fall 2015). The old lecture series had some errors and was lower quality.

For future watchers in the example he used the properties from water at 325 K instead of 330 K, he also accidentally wrote 528 * 10 ^ -8 but he meant to write 528 * 10^ -6 which gives you the answer he calculated

Thanks for catching this! We will place a correction in the notes below the video.

it is always a joy to learn from someome who likes his job and smiles while doing it

:)

[@AV-DIN]

Thanks professor for that lecture. Great job 👏

[@CPPMechEngTutorials]

Our pleasure.

[@muhammaddanish7588]

Sir how to find the nussels number for fully developed laminar flow in the tube if condition is neither constant flux nor constant surface temperature?

[@isk3804]

2:00 I calculated on my own several times on that video, and nothing was matching really so I thought I'm so dump that can't even do math calculations correctly. LOL THANK YOU FOR THE CORRECTION! Now feel more confident :)

[@yolopolo877]

yo i got a quiz what changed in the correction isn't both equation same? Im not getting it whats different :/

[@Rback189]

Hello again my king

[@treyvela8633]

seems like the properties were takes at 325 k instead of at 330 k

[@daveg2380]

Why....why did I intently watch the board cleaning as if it would be on the final? My brain is soup.

[@CPPMechEngTutorials]

Well???? Are you going to tell us why?!?!

@ 25:21 lite

[@VuyoZikalala]

Sorry, after the correction, the book says 10^6 and not 10^-6 for the viscosity. is there a conversion that was made?

[@tarifulislam7934]

Is the mass transfer included in this semester?

[@CPPMechEngTutorials]

No, just heat transfer.

[@nandanmittal4496]

Which book is being referred at 19:52. Please tell

[@aedemirel_]

The reference book is Fundamentals of Heat and Mass Transfer 'Frank P. Incropera'
