Heat Transfer (25) - Flat plate convection heat transfer examples, Flows over cylinders

Correction #1: The expressions for the local and average Nu for laminar flow shown at the beginning of class should be,
Nux = 0.332 Rex^(1/2) Pr^(1/3)
NuL = 0.664 ReL^(1/2) Pr^(1/3)
Correction #2: @7:38 The Reynolds number expression should be U*x/nu.
The audio quality is slightly degraded for the first couple minutes... sorry about that.
[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.

This lecture was recorded live at Cal Poly Pomona during Spring 2022. The textbook is "Fundamentals of Heat and Mass Transfer", Bergman et al., 8th Edition.

i believe that the output for the kinematic viscosity yields 8.06e-7 and not 78.2e-8 using the thermophysical properties on the board

[@awoldn]

7:38 - X must be in the numerator if you wanted to show the Reynolds number

[@awoldn]

10:19 the same

[@bugrahangul3740]

@@awoldn I thinks so. Are u sure for that?

19:40 to 19:55 very very important thank you

[@stephennalepa9531]

7:08 I believe your equations for the Nu number are wrong

[@user-tt2jv7us3e]

thank you that was very helpful

[@juniorjay001]

great teaching but some of the numbers he's writing in his examples are from outer space. someone buy this man a working calculator

[@alternatifoyuncu8026]

how do we find the properties from table,ı do some interpolation but it does not result same as 2:01

[@ryanm3662]

For flat plate questions 1 and 2: He writes U/VX for the Reynold's number (which is wrong), but his value for h is computed using UX/V (which is right). He makes this mistake in class because the equations on the side of the board also have this error, but his pre-written notes evidently have the correct formula.

Please provide a time stamp where this occurs so we can check it out.

@@CPPMechEngTutorials 7:38, just like Alex says below. Also he issues an explanation for the mistake during the first 3 minutes of lecture video 28.

@@ryanm3662 Thanks. We will place a correction in the show notes below the video.

Great explanation for a complex problem. You earned a subscriber. Love from India ❤
