I think you misunderstand the function of this forum. We don't do your work for you, we all have our own jobs to do. We merely offer guidance on specific topics, and most importantly, we do so on a volunteer basis.

Now for some guidance:

You need to give a LOT more information to whomever eventualy does the design work for you. You need to tell them the temperature and pressure it will be operating at, the flow rate, the chemistry of the media being used on both sides of the circuit. The desired heat transfer rate, and also any environmental factors that come into play (chlorides added for biological growth control, neutron flux in the case of nuclear reactors, that sort of thing.)

Rorschac,

I do not understand your stand. If you have your own job (and perhaps busy with it, too) you need not take pains to reply at all. Is it not a waste of your time? And I assure you, ours too. If you can not or do not wish to help, you are welcome to stay out. This forum is open for all types of queries by all. This is nobody's personal domain if you know what I mean. Another isssue I have noticed is about the incorrectness of some inquirer's language. If someone's mother tongue is not English (and that is possible, you know), he/she may make some mistakes, and that should be understandable. We are not exactly teaching manners or etiquettes here if my knowledge about it serves me right. This forum is for exchange of knowledge; if you have it pass it on, if not, stay put. As simple as that. No need to be arrogant unnecessarily. It does not serve any purpose at all. I hope what I have said will be received in the RIGHT spirit.

God Bless,

Nachi

Nachi I do not at all mind helping people out, in fact I LOVE doing so, probably more than is really good for me to be honest. That was not what I was trying to say at all. What I was trying to say was that his post was implying he wanted us to supply him with a turnkey design. Worse, he wanted it without giving us any information to work with. I was merely trying to point out to him that what he was asking for was way outside any reasonable expectation of what we do here. I was also wanting to make it clear that he understood that while this is hosted on Globalspec's system, it is not a design service paid for by corporate sponsors, it is a volunteer forum. He may not have realized that we don't work for globalspec or it's sponsors.

There is a saying that goes something like this.

Give a man a fish and he'll eat for a day, teach a man to fish and he'll eat for a lifetime.

And there is quite a bit to thermal design, efficentencies to what thermal transfer needed, volume, material, steam available, temperature as well as the design of the coil HX itself to do the job.

These are not simple yes and no answers.

Will there be a chapter on the proper selection of the beer to be consumed? I might need some additional exercises on that chapter. You know, just to make sure I fully grasp the coursework you see....

I agree and you get a GA. in fact after seeing the n number of question in the forums, all are asking us to design an equipment for him.

I was about to start a discussion on this.

Most of these are students and all these are likely their project work. We do not mind helping them, but they have a better source, their professors, who are likely to be a better source than us. A complete project design as far as i know , we will not be able to to for the,. Even do any body sreiously think that sitting here somebody will put the design of HE on a platter and - now pl go and submit your thesis ?

This is an forum for discussion of our professional problems and not do the homeworks we are more here from practical orientations and not the theritical design (a least me, though I do dabble in a bit of designing)

Look back in the forum of manufacturing and mechanical enfgineering - at least a dozen questions in last few days are on different aspects of completing their project works.

First i ask to design the pump, then filter, then the HE, then the pipelines, relief valves, safety features, controls and lo we have a lubrication unit ready.

To continue for design of heat exchnger the questionery please provide the above details

I do not want to comment on anything any more that is off topic....but I thought the nationality does not matter, nor is it typical of any one, all people are same more or less. The point I raised is relevant. But I rest my case if it is going to be merely tossed up and down and not caught.
