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
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)
Are these equations applicable for shell & tube condenser? For example, tube side is water, Shell side is R22 refrigerant, water entering tube is at 32 oC and leaving is 37 oC, Hot gas entering shell is at 80 oC and condenses to liquid at 35 oC. It would be great if you could answer my query sir. My email id kalsi@ecodivinesolutions.com
Hi, thanks for the explanation and clarification Can a doctor send this lecture on paper in the form of a PDF file. He needs the design calculations for this device, especially the mass and energy balance, and calculations for choosing the design filler. I would be grateful for you. Can you write to me on this email? alaahmel2@gmail.com
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 .
No... You can't use it..... Because currently used psychometric chart is for air at 1 atm pressure.... You can't use it to evaluate air properties at an elevated altitude due to pressure less than 1 atm
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.
how do you get C1 C2 ?

Sir u solved many problems in my project , thanks alot
This man really can't make a new video after 9 whole years...
Thank you very much! Please keep update new video.

Please can I get gas table for compressible flow...
may I know what book u were using?
Que dice? No sé Inglés:v pero igual arriba las águilas del america
thankyou sir for the great video!
Thank you so much !

Reference book ?
Thank you for great explanation
Ha, he's talking about the Blackbird. Nice. 14:15
This guy is awesome!!!!
Babacım Allah ına kurban sen çok adamsın çok delikanlısın
She helped my tank discharge
Like si estas aquí por el profe Evodio.
kyc
This guy is awesome!!!!!!
book please ?
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
Is the convection heat transfer for tube for all tube or one?
Energy conservation is violated given the temperature rises and drops with the given massflow rates!

Thank you for such a good class, just to clarify, does psycometric chart used at the video, calculated for 4300m of altitude?
No, such charts are printed for sea level usually.. For higher altitudes one has to use math equations.
No... You can't use it..... Because currently used psychometric chart is for air at 1 atm pressure.... You can't use it to evaluate air properties at an elevated altitude due to pressure less than 1 atm
Any 2d diagram of plate type heat exchanger??
I need design Plate heat exchanger ..thanks
The SR-71 only cruised at Mach 3+ at high altitude. Using sea level is a poor example.
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
I have some questions about this experiment. Who can help me with this?
33:59 Was that a fluid engineering joke? ;) Thanks for the informative lecture.
comperssible flow example in daily life , tell me sir
I need help about what is equation use in PHEs and thank you
THIS IS VERY HELPFUL THANK YOU SIR!!
Your welcome

the solving of m4 is wrong... The expretion would be m3-m1(w2-w1) m3-m4=ma(w2-w1) therefore m4=m3-ma(w2-w1)
m3-ma(w2-w1) is equivalent to m3+ma(w1-w2)
Thanks for the video ;)
ADAMIN DİBİ DİBİİİİ
What's the name of the Professor?
Nice work thanks
Nice work
Hello Sir, What the book's used in literature ?
incropra
Nothing makes me happier than watching a video of professor Abbitt from half a decade ago.
Abbitt is dope as fuck.
excellent very nice lecture
if I would give you some perameters can you design a heat exchanger for me ???my whatsapp no is 923151553342
