I need to think of some "outside the box" heating methods for a column of plastic pellets. Currently hot air is blown through the pellets to heat them. Another way is to run them under an IR heater. Can anybdy think of some alternate ways? Some sort of radiaion, like microwave? Help...
This may sound like a very stupid question, but if I have (10) one square foot aluminum plates stacked in a plate-type HX, is my total heat exchange area 10 square feet, or 20 square feet? I assume it's 10?
At my current job, I have to pay $185 per WEEK for health insurance. The employer pays 50%, we pay 50%. No dental, no vision. Have any of you ever HEARD if benefits this bad? It's really starting to tick me off...
I've heard that the Mark's Mechanical Engineering Reference is supposedly one of the most important tools an engineer can have as far as books go. Any opinions about this? Thanks very much.
Sure this question is broad and it's easy to reply by saying it's broad, but if we ignored the broadness for a moment, where are most mech-E salaries topping out these days? Let's assume you're not management, never will be, just a topped out engineer.
$80,000? $90,000, $100,000+?
I'm 6 years out of college (BSME). During those 6 years, I was (and still am) titled a "Mechanical Engineer", but 99% of what I've done has been design work, NOT full blown engineering with lots of calculations, FEA, that sort of stuff. My worry is that if I change jobs, I will have nowhere...
lease help. I have 100 SCFM of 250F air and want to transfer all of it's heat (down to ambient = 70F) to a separate 100 SCFM airflow. How do I calculate the necessary surface area?
Also, is a shell and tube design or a plate design best for air? Thanks for any help.
Please help. I have 100 SCFM of 250F air and want to strip the heat out, transfering it (the heat) from the 2" diameter tube that the hot air is in to another 2" diameter tube. How do I calculate the necessary surface area?
How long should an o-ring last (silicone or PTFE) that will be around the OD of a 6" dia. 304 SS cylinder which will travel linearly 4" (bidirectional) once every 20 minutes? It is sealing 13 psi 250F clean air.
Hello,
I am a mechanical engineer with 6 years of experience in the plastics auxillary equipment design industry. I started there right out of college. What type of salary should I be expecting? I know that this is a broad question that will probably draw broad responses...
I'm the lead...
I am in need of a high tempterture (350 F max), high tear-resistant gasket material. The gaskets are used to face-seal the ends of 10 inch and 12 inch canisters under 28 inches of vacuum (so there is obviously considerable force on the gaskets, which are currently 3/16" 70 durometer silicone...
It seems like I am always finding the need for tubing reducers. For example, I am now on a small customer request project that requires the use of a 3 inch to 2 inch 304 stainless .060" wall reducer It seems like NOBODY makes reducers this size. Does anybody know where I can get them...
