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

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

[@Oxone_2KHSO5]

10:19 the same

[@bugrahangul3740]

@@Oxone_2KHSO5 I thinks so. Are u sure for that?

[@inessogoodnolove]

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

[@alternatifoyuncu8026]

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

[@stephennalepa9531]

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

[@mehmetozdemir-ey9kb]

kinematic viscosity is 8,06224e-7

[@mehmetozdemir-ey9kb]

the vapor value was taken as the dynamic viscosity. Therefore, the dynamic viscosity value should be 0.789e-3. In this case, the kinematic viscosity will be 7.92e-7. Although the dynamic viscosity obtained by the teacher is correct, the kinetic viscosity was calculated incorrectly. the formula for finding the reynolds number in the nusselt number is incorrect. It should be Vx/v.

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

Thanks!

[@alexbrightchargeai]

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

[@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.

thank you that was very helpful
