Hey there. I am a Pakistani Chemical Engineering student...and trust me, I take help from Indian lectures most of the time. To be honest, they are a GREAT help. The teachers are expert in their profession. They teach you from the basics to the very minute details. I must say, they are spreading knowledge and for this, they will be rewarded with good. Thank You Sir. Stay Blessed.
The book used was Incropera and Dewitt, Fundamentals of heat and mass transfer 6th Edition. This book seems to be quite out of date as the 7th edition uses a more updated correlation for the external flow over the tubes, you may want to check both editions to compare.
If there would be no pressure losses required to force the flow through the heat exchanger, would there still be some power loss for a recuperated gas engine as compared with the nonrecuperated gas engine ?
I believe that the diameter used in the calculation of the Shell side Reynolds number should not be the same as the tube diameter (19 mm). The diameter should be, D = Aeff / Perimeter. Aeff is the area of the inside shell minus the area of the tubes, and Perimeter will be πDs( Ds is the inside diameter of the shell)
I think you must not to introduce a correction factor for DELTA (T ln) because in your example you are working with a 1:1 heat exchanger (single pass in tubes single pass in sheel). This is a very close situation to the one that is present in double pipes exchangers, were Delta (T) ln is a valid measurement of temperature diference. That graph is made for single pass in shell and a pair number of passes in tubes. FT=1
Hi, i need to design Heat exchanger for my project. The hot stream temperature is 75 and 25 for inlet and outlet respectively. heat duty is 4.018 kW. now i'm planning to use water to cool down the substance. But i don't have any info on its properties. I've read that maybe 21-22 deg C is an ideal for the inlet. but i can't determine the outlet because i don't have the flowrate of the water. so how am i supposed to determine the flowrate or the outlet temperature? Please help, i'm stuck because i can't even calculate the LMTD
Sounds like you are using water, cooling water. Generally cooling water. Temperature rise is limited to 115 degrees F. This prevents salts from dropping out. Consult Kern if available.
The cold fluid certainly is not water, because it has phase transition between Tci and Tco, so Cp(Tav) can not be an approximate value. If it is assumed as water, taking the phase change into account, q=h(Tco)-h(Tci)=7195 kW, not 998.4kW!. What are the cold and hot fluids? It would be much more beneficial if you provide this information
Ok im not an expert, i just want to know how did you get the Kf to calculate heat transfer coefficient, and what it means please I can't find it in the book.
Very useful.Thank you very much Sir. Please let me know about your e mail addresses so that I could communicate with you in case of a practical design which I expect to do .
Sir u solved many problems in my project , thanks alot

Its quite comprehensive but kinda raises a few question which are unanswered. A good effort though and will help beginners.
Keep up the good work.

How about with Book of Heat Transfer from DQ Kern?
Waouh, you are wonderful !!!
thank you, for this very inspiring lecture !!!
THANK YOU SO MUCH !!!
This has been very helpful for me.Great Job!
thanks for such nice explination. keep it up 👍
Thank you very much!
Please keep uploading!
congratulations! , thanks for sharing your knowledge, it's quite useful (Bolivia)
its a very nice to see this video is very useful, and thnx of you about this vedio.,
thank you for spreading knowledge sir !!
very informative lecture, thank you
If there would be no pressure losses required to force the flow through the heat exchanger, would there still be some power loss for a recuperated gas engine as compared with the nonrecuperated gas engine ?
I would like to know how the outlet temperature and the outlet mass flow rate was calculated.
Is the convection heat transfer for tube for all tube or one?
thanks man that was a huge help
how do i go about the design of a finned tube HE? thank you in advance
Thank you it is so useful for me and mankind
This is a very much helpful video.
Thanks very much, you make it nice and easy.
Helpfull video. Thank you.
thanks,,,good lecture!!
Nice work
may I know what book u were using?
Which factors are involved in heat exchangers??
How did you use film temperature despite the lack of surface temperature knowledge,sir?
how do you get C1 C2 ?
great lecture

Good lecture.plz made for distlln coloumn also
INFORMATIVE LECTURE ON HEAT EXCHANGER
nice lecture video
Thank you so much !
Thanks for the video ;)
I need help about what is equation use in PHEs and thank you
thankyou sir for the great video!
Babacım Allah ına kurban sen çok adamsın çok delikanlısın
thanks , what's the book u used to get the figures ?
fundamentals of heat and mass transfer by Incropera and DeWitt, 6th edition
33:59 Was that a fluid engineering joke? ;) Thanks for the informative lecture.
Quite explicite please can i have the link to have the textbook used to obtain the values from tables pls its kind of really urgent
thanks this has been very helpful to me but I just would want to know why you assumed there was no fouling??
because it's clean, but u right it's not a good assume when we are designing of heat exchanger
THIS IS VERY HELPFUL THANK YOU SIR!!
Your welcome

what is the final BF of this solution?
I like this lecture
At the 31:21 minute mark, for the Length calc "L = 2.77m", how do the C and K temp units end up cancelling each other with no convertion ?
if you raise 1 C for some liquod you also raise 1 K.that is why

Thank you teacher¡¡
in which book you look for cp at ave temp.??????
Perry handbook will help u
.
Thank you very much! Please keep update new video.
please give a similar lecture considering U TUBE HE
Ok im not an expert, i just want to know how did you get the Kf to calculate heat transfer coefficient, and what it means please I can't find it in the book.
You can find kf in appendix A table A.6
kf is the coefficient of conduction of fluid
what is the name of the textbook used in this video?
Fundamentals of Heat and Mass transfer by Incropera and Dewitt, 6th Ed
thank you, sir!
Any 2d diagram of plate type heat exchanger??
Hello Sir, What the book's used in literature ?
incropra
book please ?

Very useful.Thank you very much Sir. Please let me know about your e mail addresses so that I could communicate with you in case of a practical design which I expect to do .
Reference book ?
I need design Plate heat exchanger ..thanks
