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.

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?

Sure, and so then you are suggesting that the user create a table based on temperature measurements for all possible ambient temperatures which may be encountered in the environment in question? If so, there are tables which are already prepared available on the net, I guess. But I thought that the question was "how to calculate"....

AS PROMISED: Here is 1.5 Kg Bread Loaf with NO SUGAR ADDED (all other variables were held constant) Conclusion: a. Smells like bread b. Tastes like bread c. Looks like....a what? Does it have one leg on it? Maybe a snail? Something. What I learned: I must use a minimum of 1 Tablespoon of Sugar in order to get the yeast producing CO2 faster, maybe... Still, I will eat it, for sure. And, I would also serve it to guests. This will be good added to chicken stew.

Just use Physics.Stackexchange IF you don't believe me... https://physics.stackexchange.com/questions/91792/realistic-calculation-of-heat-loss-for-pipe This is NOT an engineering problem, per se. This is a simple Physics problem. But, STILL, I already linked, previously, a very helpful link specifically focused on heat loss from a pipe, which will generalize to all environmental conditions. (INCLUDING the radiative heat loss due to infrared radiation from the pipe, and the color of the pipe, by taking into account blackbody radiation, which IS mentioned on this site, and which I DID mention before in one of my previous posts, too.) So then...what's the problem?

This is my point. Do you not understand it? If you test in conditions where the ambient air around the pipe matches the temp inside the pipe, then there would be zero heat loss (except for the radiative heat loss from the steel pipe). Therefore, such a calculation based on the "approach" suggested earlier would be MEANINGLESS for practical purposes of calculating convective and radiative heat loss when the ambient air is at different temperatures, say zero degrees, 50 degrees, etc. (Do you not GET this simple concept?!!!) IF the OP had said that the AMBIENT AIR TEMP will ALWAYS remain the same, then, the approach mentioned earlier could give an APPROXIMATION, but ONLY based on measurement of outlet and inlet temps, and ONLY based on the accuracy of the temperature sensor. In addition, the radiative loss from the steel pipe would DEFINITELY depend upon the COLOR of the steel pipe, since we all know about BLACK BODY radiation, do we not? (I.E. a black pipe will radiate MORE HEAT than a SILVER PIPE. NOW...do you GOT IT????) Use the formulae in the Engineering Website that I linked... Simple!

Sorry, but wrong, I think. Example: Inlet Temp = 170 Degrees C Ambient Temp (around pipe) = 170 Degrees C Outlet Temp = approx 170 Degrees C (maybe slightly lower due to radiated heat from pipe) So: You say you could calculate heat loss from the steel pipe in all ambient-air conditions using the approach you approve of? Simply WRONG. Because...You canNOT. Correct?

Making that simple calculation would NOT generalize to all conditions if for example you tested when the ambient temp was high, one day, your determination would NOT apply to heat loss when ambient temp was colder. Please refer to the good site which I linked in my previous comment.

You will find a very thorough discussion on this good site: https://engineerexcel.com/heat-losses-from-pipes/

Concerning your worry that she may suffer from Asberger's Syndrome, and you from Paranoia... You don't sound like you are paranoid. And she doesn't sound as if she is on the Autism Spectrum. I would say that you haven't known each other long time. I am a high-functioning Assberger, and I would know. I am also paranoid at times, but for good reason. So here is my very best advice for you... What you need to do is begin attending her uni classes with her. See how she interacts with here classmates and profs. Eat with her at the uni cafeteria. If you follow my good advice, all shall become clear within a week. Then, you both can decide if you wish to pursue this romantic relationship further. No charge for this internet consultation, by the way.

Is this PUN intentional? Do you mean that she is physically sore? Or do you mean she is sore (angry)? I may be fatigued, but still remain curious about this topic. Clarification is needed on the two points I have mentioned, the distance question, and now this sore question. Or, did you mean she said she had a sore throat???

I beg to differ. This seems completely like me, to me. I think that I may have consumed too much Gary Larson when I was at the impressionable age. I often see the world through the lens of The Far Side. Perspective is crucial to our perceptions of Reality, I think.

Your Topic makes NO SENSE: a. You have a Tiny Small condo b. You say she is distant c. HOW can she be DISTANT when your condo is so small? Totally Illogical Topic.

To Those, Like Me, Who Wish They Were Inebriated: When I was younger, like about the age of 15, the parents of my chum would sometimes give parties for the execs working under my chum’s father at his Oil Company. For some reason, at that particular time in history, The STINGER was a very popular drink. After a few hours of partying, and when it was time to leave, the guests would get in their cars and drive off, not before backing over the shrubs and flowers on the way out. The next morning, the hung-over father of my chum would scream and curse his guests, a blue streak. The angrier he became, the more delicious for us, simply because it was he that controlled the booze, and therefore he was obviously partially culpable for the destruction of his bushes. But what we enjoyed most was to wait for the adults to get so drunk that they would no longer care if we, too, began drinking Stingers. When I was young, I recall that we could drink up to 10 Stingers per man, and the experience was amazing! Stingers are sweet and powerful, and the flavor is also extraordinarily good if you only drink the expensive stuff: I wish I could return to those days and drink like that. What about you? But these days, I wouldn’t know what to do with a Stinger, maybe… Because, expensive straight Cognac would be better, now, in my humble view. Regards, And not even a little bit tipsy, Gamma

For me... Thinking is a lot of work.
