Very true about the testing. Humans are able to detect some odors at levels that testing equipment will often miss (1 part per billion for skunk smell). These are the only chemicals that we can smell as well as other animals. These chemicals also tend to be harmless and biodegradable...
I think I found what you ment...and it is as I hoped it would not be. Just to be clear what is DLable?
In those examples one has to either define every hole or have the holes linear pattern down the tube centerline. Unfortunately there seems to be no way to easily do this. I have come up...
The problem I am having with the curve driven pattern is that the pattern items do not rotate correctly with the helix. If a pipe were to be inserted through the holes they would no longer intersect the centerline of the pipe.
ctopher I do not understand how that would result in holes in a...
Is there any way to create a circular linear mixed pattern. For example if you have a thin walled tube and you want to put a heliptical series of holes in the tube.
Basically telling SW to step down the tube 1 inch then rotate 30 degrees and pattern the profiles.

Everyone please copy these and keep them on a cd (if you need to use them) to pass out. The site is very helpfull as a review and if the bandwith gets too high they might take it down.
I hope this helps all you older guys who...
cuky, your first link list the average with the base titles around 67k for all disciplines of plain "engineer". I completely believe this. However if you factor in the additional pay for lead, chief, supervisor, manager, PE, etc (all titles that are likely left in another column although they...

I am going to have to disagree with your information on salaries. From personal experience and all the salary cross sections I have ever seen your numbers are way low.
Where did that information come from?
For instance the average STARTING salary from my uni was over 50k/yr. This...
As stated you need to consult the ASME code. However I did find this within the ASTM A 283 standard.
here is an internet link

ASTM A 283 covers low and intermediate tensile strength carbon

This will allow for not only the standard sizes but UNS threads of your imagination. I have not checked them though.
Anyone care to verify their output?
JMW, Apparently I am not being completely clear here.
I do not know any individuals within the FM organization. I was wondering if anyone here had a contact that I could speak with.
Chemfemme, I don't feel the report needs to be anynmous.
Thank you for the time in answering.
I have already verified the approval. I am in the middle of preparing a report and have to say that just writing it is enough to make one feel sick.
Really your last paragraph gets to the meat of the situation. I have thus far been unable to find a...
I have to ask. If the inspector is so worried about small voids around the output area of the pipe why are they not worried about the volume inside the pipe itself?
I believe that somewhere along the way some things were missed. Let me clear them up.
#1 the product does have glaring safety issues, and considering it is used in hazloc there is a danger to personell and property.
#2 The moral question of "should I do something" has already been answered...
IR stuff as stated in the first pose FM (factory mutual) is the approving NRTL on this.
EddyC The company is on board and understand the ethical responsibility.
The real question is if you find a product that is approved by a NRTL (FM specifically) how do you alert them WITHOUT challenging...
Greetings all, and thanks in advance for any replies.
I would appreciate a little adivce and possibly a contact on who to take this to.
As an engineer who works in R&D, is lead engineer on all our NRTL projects, and generally considered a smart cookie a problem has come across my desk. One...

I believe that you are looking at the small picture here. To make the assumption that the junction temperature is already maxxed out in most "real" applications is just a leap of faith. I personally work in R&D. When I look at a junction temperature it is never defined...
As for Ko99's statement. It is generally not the case that you will have fins that are wider than they are tall. It is quite common to have a fin height 10x the width. As the height of the fin increases or the width decreases you will see more effect on the fin efficiency with a reduction of...
Guys don't forget that the ss far away from the bolts could still cause a galv cell. Don't just consider the bolts when looking at surface area. Is this system being bolted to the building frame or an isolated structure.
You should try to isolate them if easily done so. However, it seems...

I beg to differ. As a bit of a throw back to older day I had a professor (about 70 years old) who made everyone in a senior class on polymers state if they had a job or not and what field said job was in, or where they were looking.
More than 50% wanted to work...
