Hello!

Does any body have Crane's Technical Paper# 410, if yes, please make it avaiable for download.


Thanx

It costs only 36USD.
I think it isn't much, especially when you see what's inside...

binzee:

I have 3 copies of Crane's Technical Paper No. 410 and others on this Forum probably also have various copies that we've bought throughout the years - or had corporations give it to us as complimentary copies which they paid for.

I direct this message to you and to ALL OTHER STUDENTS on this forum: If you try to solicit illegal, copyrighted copies of software and/or other copyrighted material (like Crane's Tech Paper) on this Forum and I spot it, I will immediately DELETE your posting. I will assume the best impression of your post this time and take it that you don't know that you are dealing with copyrighted material - or that you don't know what copyrighted material represent. I also assume the best from your character and upbringing: that you respect the property of others and that you would not steal or cheat others from what rightfully belongs to them. I have gone over this subject many times in the past and frankly am very disappointed that some ChE students still stoop to think that there are free lunches and free rides in this world. That is true only in the criminal sense, when you steal from others, or take what is theirs without repaying them. However, even then there is a "payback" eventually.

I believe Zauberberg, in trying to be polite, did not state it the same way I do. However, I also believe he would take the same position with respect to the property of others. If we need what others have labored to produce, we must rightfully pay them for it. This is not only morally correct; it is also ethically correct. The two go hand-in-hand.

I have taken all the examples from Crane's Tech Paper and converted them to an Excel Worksheet - to show how fluid flow problems are resolved on a spreadsheet. I will share these with students on this Forum in the future. This is not a violation of copyrights. I did all the work and I'm not profiting from it.

However, to circumvent the sale of Crane's by copying it into a .pdf format and then distributing it without permission from Crane is to steal from them. The same thing applies when someone copies a simulation program and distributes it without permission from the owners. Please don't resort to doing that --- at least not on our Forums.

You are right, Mr Montemayor. Thank you for your detailed explanation of what I was trying to say. Crane Technical Paper #410 is a true engineering fortune, compared to its low (economic) price.
I believe many people, especially students, would like to catch as much occasions as they can - to reach expensive software or e-materials that are otherwise unaffordable to them. Too bad we are living in a cruel world, so we do not have all equal opportunities...

I would like to use this topic to ask you if it is possible to upload many of PDF or XLS documents from my e-library, which would be useful to many of forum members, not just students.
At the time when I had reached them, they were all free (ePTQ magazine, for example), but now you must paid to obtain a copy. Is it legal to upload these articles and spreadsheets, without violating copyright laws?

Thank you again, sir.
Best regards

Zauberberg:

Your question is valid and poses a problem for me to answer. I haven't done enough research on the subject of magazine articles, other than I know you can retype them and freely circulate them. That way you are not copying the product. I have done this with some classical chemical engineering magazine articles that I did not want to lose due to wear, tear, and age so I have typed them into a corresponding spreadsheet. I have done Hooper's famous article on 2-K friction calculations, Hill's article on gravity flow calculations, etc. But I haven't looked into free articles. I believe the answer lies in looking at the magazine itself and reading to see if it is copyrighted and permission is required to copy the material.

The real answer lies in the opinion of Chris Haslego, the owner of these Forums. I recommend you write him a short email explaining your idea and I'm sure he can give you a quick and accurate response as to the viability of such an idea. You can reach him through the Forum's email.

Let us know the result.

Hi Art,

I am very much interested in your spread sheet on the Piping Size calculation. I hope you will be sharing you worksheets soon on this forum.

Regards.

Please take a look at the main site ( http://www.cheresour.../software.shtml ) and see if you can find what you need.

Replying to Art's message above:

This is always a tricky subject to address. Every piece of technical information on the internet takes time, energy, and usually money to produce. Every organization has their reasons for producing such content and when they produce the content, they own it in the form presented.

Quoting from www.eptq.com's Terms:
"2.4 Subject to the above, you may retrieve and display Content from the Site on a computer screen, print individual pages on paper (but not photocopy them) and store such pages in electronic form on disc (but not on any server or other storage device connected to a network) but you may not reproduce, modify or exploit any of the Content for commercial purposes. "

This statement would prohibit the posting of their content in whole form on our message board. If there were a piece posted and they requested that we remove it, I would do so immediately. On the other hand, if a page or two from one of their articles was posted to specifically address a question posted on the board, this may be considered fair use and they probably wouldn't have too much of a problem with that as long as that article was freely available at some time.

Over the years, I've seen (and still see) entire copies of our free articles from Cheresources.com on other servers. Usually, these articles are in server locations that are meant for internal company use and education. In those circumstances, I don't really have a problem with that as there's not intent to profit from our articles. Now, if our premium content were to appear freely available on the internet, obviously that would be different as it would inflict immediate financial harm to Cheresources.com (and inhibit us from producing even more free content). I would have a big problem with that.

In short, it's important to execise common-sense judgement in using and distributing unlicensed content. Before doing so, simply ask yourself this question, "Will this financially harm the copyright holder if I post this content." If articles are used as I've described above, you probably didn't "save" someone from subscribing to a journal, but if you uploaded a dozen articles from a given publication...that's most likely a problem. Notice that the term quoted above explicitly states that their content is not to be used for "commercial purposes".

Finally, if you do use information from a given source, providing the proper credit to them in your post is always a good idea. If you use someone's information resource, and cite them (thereby marketing them further), there's less of a chance that they'll feel "invaded" by the use of their information.
