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.

n for Pr number should be 0.40 since it was heating

shouldn't it be pradtl raised to 0.4 for heating of turbulent internal flows rather than 1/3

i think it should be 0.4 too

No, it is valid for "turbulent internal flows". Pr^(1/3) is used for "external flow (flow over cylinder)".

he corrects himself later in the video at around 36:20 for a different problem. He forgot to correct it in the earlier problem, though

Im wondering the same thing.

Nvm, so, all the variables are known, then he just solves, look at the check marks.
