Pud-
Dupont Delrin 100ST. Word through the grapevine is they are unable to source/produce one of the critical additives/modifiers, and several other resin manufacturers/compounders are similarly unable to provide their catalog equivalent material.
I am researching alternate injection molding resins due to material supply availability (i.e. we're about to run out of our qualified material and can't get more). Use case is for threaded fittings.
Specifically, I'm wondering what material properties are most important when considering the...
Hello all-
I've recently started a new job (my 2nd since getting my BSME). I moved from a company that wasn't big enough to be considered even a "small" company into a multi-national behemoth with all of its associated procedures, planning, and documentation. I appreciate the structure...
As a young engineer, I would reply with this advice-
Yes, you made a mistake by saying "no" to your old boss. At this point, that is done and in the past, so just move forward.
If your new boss is your direct supervisor, that is who you should be contacting for work if you need something...
So it sounds like the required ventilation is 6 or more room changes per hour, with higher ventialtion capacities required if 6 RC/h is insufficient to maintain vapor levels below 25% LEL. Kind of like a car warranty: 5yrs or 50k miles, whichever comes first. Only here it's "whichever is greater".
I am not an expert when it comes to ASME B&PVC, but my understanding is:
(1) Just because something doesn't technically fall under the "pressure vessel" definition as indicated in Section VIII, Div. 1, doesn't mean it can't be fabricated to those standards and U-stamped. I would have to sit...
I think there's a distinct difference between idle small-talk and actual interpersonal skills. While I'm not going to be rude to colleagues, I also have work to do and don't really need to know about your flat tire or your son's soccer game. Small-talk has its moments, but they are relatively...
waross- Thank you very much. I greatly appreciate your taking the time to dumb it down for me. I'll look into getting an autotransformer to step up the voltage ~20% and swapping out the capacitor for one with ~70% rated capacity.
itsmoked- Yes, I am [smile]. I'll admit that I probably would...
I'll pile this on here, if you gentlemen don't mind... I'm afraid my tiny company has no electrical engineers around for me to pester, so I'm left to bother you all in the hope you'll grace me with some much needed knowledge.
Trying to calculate PF
115V/1Ph/60Hz motor, 1.10A, 3250 RPM, 1/8...
So reading the FAQ, my take away is:
--50Hz motor to 60Hz supply, constant voltage- generally you're ok as far as the motor goes as long as the increased load HP requirement due to higher RPM doesn't cause the full load current to rise above the current shown on dataplate. Biggest issue here...
Thank you. I'll admit that I have not used the FAQs before and did not realize that the website search does not automatically include them when searching for a topic. I'll be sure to check there first in the future.
Hello EEs-
For reasons that are somewhere between "trivial" and "pipe-dream", I am trying to learn about the viability of utilizing a centrifugal pump with a nameplate rating different than the electrical supply. I've poked around this forum and gleaned some understanding, but I'm afraid the...
Thank you for your replies. Not sure why I didn't think about a 1x1x3/4" reducing tee earlier. Probably would have gone that route if I'd thought of it sooner. Unfortunately, I believe the spool in question is needed to be finished tomorrow to be assembled and sent to painting. I think, in...
I know this topic has been beaten to death, as I've gone through pages of search results on the topic. I wanted to throw an application/proposed solution out to see if there might be something else I should consider.
1" Sch.40 SA106B pipe requires a 1/2" NPT connection on the side. GTAW...
Did your co-op position not "excite" you, or were there other factors that prevented you from being employed there after graduation? I ask because most of the guys I know who did co-ops turned around and had full-time positions with those companies months ahead of graduation.
University career...
HornTootin EE- I absolutely agree. The analytical skills I had (athlete's raw talent) were certainly honed through my education. But that first step is a doozy when you're all of a sudden playing in the big leagues and there are previously-unseen things like standards/codes and a lack of...
As a green engineer, I'd like to toss in some viewpoints from the bottom of the ladder.
I participated in most of the things that have been mentioned above as contributing to "horse sense". From toys as a kid to tearing down and rebuilding stuff- either to fix it or just because I could- to...
I am reading your question to be, "What is the reason for [your] company not allowing threaded joints on pipelines carrying flammable fluids in equipment, despite the fact that it is common practice (exhibited by the fact that so much equipment from other companies use threaded joints)?" If I...
Is there a better forum to direct this thread to where active members might have a resource or two to point me towards? I assumed this was the right place, given it's the fluid mechanics forum, but perhaps there's a different forum where my question might get addressed? I recognize most of the...
I am including specifics to the problem I am currently tackling, though I hope for this to be a more general, qualitative question about nozzles and supersonic flow.
So I've been tasked with developing a "new" product at my company. We create a vapor blending machine using a...
