This seems to be the lecture my professors are using as a template for teaching in class. I am excited to finish the 60 lectures asap!

Teaching is much better if you don't slow down everybody by your writing speed. Edit the video to fast forward when you are writing. See some of the excellently produced lecture videos from the U.S.A.

Please sent to me as PDF formHydrogen at 15 ºC and a pressure of 1 atm. is flowing along a flat plate at a velocity of 3 m/s. If the plate is 0.3 m wide and at 71 ºC, calculate the following quantities at x = 0.3 m and at the distance corresponding to the transition point, i.e., Rex = 5 x 105 (take properties at 43ºC) (a) Hydrodynamic boundary layer thickness, in cm, (b) Local friction coefficient, (c) Average friction coefficient, (d) Drag force, in N, (e) Thickness of thermal boundary layer, in cm, (f) Local convective-heat-transfer coefficient, in W/m2-ºC, (g) Average convective-heat-transfer coefficient, in W/m2.ºC, and (h) Rate of heat transfer, in W. Consider a 15-cm x 20-cm printed circuit board (PCB) that has electronic components on one side. The board is placed in a room at 20°C. The heat loss from the back surface of the board is negligible. If the circuit board is dissipating 8 W of power in steady operation, determine the average temperature of the hot surface of the board, assuming the board is (a) vertical, (b) horizontal with hot surface facing up, and (c) horizontal with hot surface facing down. Take the emissivity of the surface of the board to be 0.8 and assume the surrounding surfaces to be at the same temperature as the air in the room. A shell-and-tube heat exchanger with 2-shell passes and 8-tube passes is used to heat ethyl alcohol (Cp = 2670 J/kg · °C) in the tubes from 25°C to 70°C at a rate of 2.1 kg/s. The heating is to be done by water (Cp = 4190 J/kg · °C) that enters the shell side at 95°C and leaves at 45°C. If the overall heat transfer coefficient is 950 W/m2 · °C, determine the heat transfer surface area of the heat exchanger.

thank you so much step indian

Can anyone explain how sir wrote the accumulation term?

old is gold

pls give mathematical derivation or concept links for past few lectures(bessel's function,orthogonality condition,etc) as most of them don't have same mathematical prerequisites required for solving heat transfer problems. i have heat transfer in this semester but math required for heat transfer is in upcoming semesters.

Awesome sir

It was very good!

Why the centre of symmetrical heat profile consider as adiabatic sir? Practical explanation please sir!!

Sir while seeing plane wall with generation u said that "when we have heat generation we can't use resistance model concept " And then in example sum u used the resistance concept to find T1? while we have heat generation at slab A how we can use resistance concept sir

best sir

Thank you for the great helping tools you have delivered, sir.

One of the best lectures in my life. Thank you Professor. If possible please provide lectures of mass transfer and thermodynamics

This was one of the best Heat Transfer Course I've seen. Apart from having a brilliant mind, Prof Ganesh is an excellent communicator. He breaks down such complex concepts into understandable and digestible bits. His coverage on Convection and Radiation is absolutely brilliant, people make these topics so complex, yet Prof is able to break them down into simple intuitive chunks.

THODA HIGH LEVEL HO GYA SIR

Why did we have to stick the thermocouple at x=0? Any other point would have worked just as well, right?

Thank you so much sir for such a vivid explanation.

Thank you sir for explaining in such a better way.

who hired this cameraman

The board is not visible properly

Appreciable explanation

It was a phenomenal explanation

Poor videography

Outstanding Explanation!

helped a lot for my ct prep . tq sir

This Tamil professor is so perfect to teach tough subject in a very lucrative way. ❤️

thank sir for giving such very passionate lecture of heat transfer

Tq you sir love u a lot❤❤

ty very much sir

3:40

The explanation of the concepts is not up to the mark as compared with IIT Kharagpur or Madras lectures.....

10:00

Typo: The term indicated at 22:09 in Rohsenow correlation should be raised to the power "3".

Thanks sir

How did you calculate T1

worst cameraman

How did we get Cn

Sir..its best lectures.. for heat transfer...
