Anyone here truly wishing to be able to CALCULATE Heat Transfer...needs to watch this good series of lectures. This series actually shows you how to do the CALCULATIONS, and consider all variables, including the ones I mentioned above in previous comments. ALSO, this shows how to do the calculations for heat transfer which is BOTH linear and non-linear. And, this series shows how turbulence affects heat transfer, as I also mentioned above. Some commenter stated that I was providing pseudo-science examples. But, if you watch these lectures, then you will see that I was NOT. All these variables are discussed AT LENGTH in this good lecture series. There are 37 Lectures in this Series. Maybe NOW the guy that commented earlier, and who provided his useless approach will....See The Light? THIS is NOT pseudo-science:

1.5 five-egg omelets. Heel of bread, toasted, topped with sunflower oil. High-quality iced tea from Sichuan mountain tea plantation. No sugar. No STINGERS. Breakfast taken in the nude. AC turned up. Ambient room temp 19.5 degrees C. Such is breakfast-hour for me in my gilded cage, in this neo-gilded-age.

Unfortunately, it seems that the American Pendulum continues to swing strongly in the wrong direction. What to expect? Now, with increasingly pervasive use of an AI-influenced Internet, even History will be totally lost. America's population will become increasingly fractured and fragmented. And America will soon become, to paraphrase Ronald Reagan... The Looney Bin on the Hill.

In order to make the calculations to solve the homework problem: You will need to use calculus because the fluid in the pipe will continuously change temperature as it flows though the pipe. So you will need calculus, as you probably know. This is a perfect calculus problem, in fact.

OK...then... Would it not be good to carefully formulate you questions, and then post them on https://physics.stackexchange.com/ You will get better feedback and learn more by doing so; there is little doubt. Homework is for LEARNING. It's not for cheating yourself by finding shortcuts. Learning is Good. Shortcuts do not work if one is trying to learn.

You are correct, of course. Mistakenly, I seemed to have focused on the long hair, and then I came to an erroneous conclusion. This is a very good lesson for me to learn, that I must be more observant and also must not jump to conclusions by letting my perceptions carry me away. And, as you say, my word choice was incorrect. Why I used the word RINGER, I do not know. I must have been thinking of horse racing and betting on the horses, I guess.

YES! The guys on this thread just DO NOT GET IT! If we are talking about some sort of homework problem for either an engineering school or for some Physics student, at an advanced level, and worthy of consideration, there is NO WAY in the WORLD that some REAL WORLD engineer is going to face the following scenario: a. We are building a building with a steam conduit b. We need to know the heat transfer of the steel pipe so that we do not too much heat up the room through which the pipe passes. c. But, don't worry, because we know you know nothing about Physics. d. So, we will build the building and steam conduit first. e. After completion, we will send you up to the 28th floor so that you can take your itsy-bitsy thermometer up and measure the outlet temp from the steel conduit, and then use what little Arithmetic you might know to do your multiplications. Outlet Temp is NOT part of this homework exercise if it's to be for either an Engineering school or Physics class. Also, what's with all this emphasis on.... CONSERVATION OF MASS, CONSERVATION OF ENERGY, CONSERVATION OF MOMENTUM, etc? !!! It's like we are back in 7th-grade science class, or something. YES, of course, we are speaking of Classical Physics, and so OBVIOUSLY we know these things are conserved! It's not as if we will be converting mass into energy in this steam conduit, or whatever! And why do these guys insist upon turning this homework problem into one of taking measurements? They are not talking about calculating. They are talking about MEASURING!!! What good is that, in this case? Therefore, if someone is learning about how to do calculations of heat transfer through a wall, a cylindrical wall, etc., they should FIRST look at the site https://engineerexcel.com/heat-losses-from-pipes/ and learn the basics. Then, they can post some intelligent questions on https://physics.stackexchange.com/ But, please, when posting your questions on the physics.stackeschange, do have your questions well conceived. And, BE POLITE and RESPECTFUL... And do what I say, and not as I do...

Ringer meaning imposter. As in my landlady must be an imposter. Also I guess I innocently mistook the person with long hair to be a woman.

In order to do this homework question justice, then it would really be necessary to apply principles of Fluid Dynamics to determine variables such as turbulence of the fluid in the pipe, which would affect heat transfer through the wall of the pipe.

I actually think this could be a nice little homework problem if the ambient temp was known, and if the fluid type and pressure was known, etc... Because, if the inlet temp was known, then one would need to calculate heat transfer through the wall of the pipe, as the fluid travelled along the pipe at 8 meters/sec. Which would necessitate calculating the instantaneous change in temperature of the fluid as it cooled while passing through the pipe, as this would also cause the instantaneous heat transfer through the wall of the pipe to change. So, sounds like a calculus problem to me....

Yes, you did advise me of this before. But, I had only that instant yeast in the brown bottle from Tops. I will try again, with zero sugar, when I can get what you suggest......THANK YOU!

OK... NOW I agree with you. There isn't enough information in the "homework question" to be able to arrive at any answer. However, It is still impossible to measure the outlet temp of a pipe that does not yet exist. And, the formulae of MOST value to calculate heat transfer (total including due to radiation and convection) are clearly explained in the website I linked initially, And further, this website should be of most interest to the student, or whomever is interested in these types of calculations. Do we design first and then build? Or, do we build first, using any old random materials and dimensions, and hope for the best? Should we just build first, and then make revisions later, based on outlet temperature measurements taken after the fact? Doing so surely would boggle the mind.

OK... LET'S BE CRYSTAL CLEAR HERE... If this is a homework assignment... There is NO MENTION of knowing the outlet temperature. There is only mention of knowing the inlet temperature. Therefore, since the HOMEWORK QUESTION does NOT supply the OUTLET Temp... You guys CANNOT use this NONEXISTING DATA to CALCULATE the answer and Complete the Homework Assignment. How many guys here have studied Physics at University? My answer would be .... e) None of the above This is NOT a troll post as some guy asked in a comment above. This boggles the mind.... Sorry.

The POINT is answering the OP based on Physics. And, your approach of taking temperature measurements from a pipe that is still in the design phase, not yet built, is IMPOSSIBLE. But, you don't get it. And, don't think your mention of elementary basics such as conservation of mass, energy, and momentum will help you to sound more credible in this case.

What about heat loss due to convection? Or, don't you worry about discriminateing between the two?

I could. Easily. Better to save my Tea Rant for my Tea Topic, Tomorrow.

Maybe. IDK...

Jackie Gleeson wasn't handsome? BANG ZOOM!

Please opt for Chinese tea, only.

Yes, but the tenant is a tramp.

Alcohol is not conducive to a more self-actualized life. Most theoretical physicists choose not to drink because they prefer to theorize. Top computer coders drink Red Bull or similar. And top sexual athletes shun the booze.

What you FAIL to COMPREHEND, so strangely, is that your approach FAILS miserably.... In the case where the system is in the DESIGN phase, which is crucial. Probably EVEN YOU will not be able to to take temperature measurements on a pipe that has not yet been built. Or.... Can you?

OK. Good. Let's just wait and see if you are able to stay on an even keel.

Now is the "Day After" the very boring Beerless Day... So, will today be another boring day of no beers? Or, was the Yesterday with No Beers, boring enough, already?
