Hi everyone, it's been a very long time since I had to use my heat transfer knowledge, and the internet is coming up dry with explaining what is involved in the calculation I'm trying to do.
I work for a plant that produces dry food mix that is mostly flour and sugar, and we cool some of our...

I couldn't find any previous mention of this on here, it seems to be brand new news. What do you think, bull or not? I'm inclined towards bull. I haven't done thermodynamics in so long that the charts don't mean much to me anymore.
There are a...
Hi guys, sorry to bring up an oil additive topic on here, however I've had very little luck getting coherent answers to the question as to whether or not it's safe to use Liqui (Lubro) Moly's MoS2 additive in a wankel engine, specifically on my rx8. I aim to decrease wear, especially on the apex...
Hi guys, I'm trying to find a way to get olive oil and caustic to react in order to clean olive oil processing equipment. I'm having a hard time getting much of a reaction to take place. I;m really trying to keep costs low on this, I know there are pieces of equipment such as coloidal mills or...
Hey guys, I've been asked to provide structural calculations for containers that have been braced to hold water. I know that the way the system is designed works, I just need to prove that it does. I just don't have the vocabulary to look up what I need online to find the equations and I need...
I recently read this article
http://www.wired.com/autopia/2010/10/the-chevrolet-volt-isnt-a-true-ev/
What struck me was the fact that the volt is a series hybrid, something I didn't know about the car until I saw this article. What grabs my attention isn't that the car isn't a true EV, that...
I need to blacken some stainless steel parts and was told that heating them up to around 600 degrees C would do the trick, but half a canister of mapp gas later I'm convinced that's a load of crap.
I found some chemical coating kits for sale on the internet but I'm very sure that I could get...
Hi guys
I'm active on some of the other forums, but I have little to no knowledge of electrical engineering so I don't know enough to figure out the answer to my question. This is for a story I am writing so I'll break it down into some logical steps.
1) Will an EMP or high frequency radio...
I'm looking for the best possible airfoil out there for a wing-in-ground-effect section that is inverted in order to generate downforce, the airfoil has to generate as little drag as possible whilst maximizing downforce. The requirements are a bit of an oxymoron, but please advise on the best...
We're treating the wastewater from a raisin production facility, and the first step once it leaves the collection area is to get pumped into a settling tank, where the water is then pumped out by a submersible pump. All the rubber of the power cords to the pumps and the float switches is...
Hey people,
I'm looking for papers, books or just any information you might know regarding the wing-in-ground-effect (I'm going to call it surface effect to differentiate from the other anti-lift ground effect). I need some general info on it, but going specific, I also need to know what the...
I know this might not be the best place to post but I can't think of where else to do it.
I'm looking for some form of anti-microbial grease or paste to use in the door gaskets at a winery, we're having problems with film yeast and bacteria growing in these pockets and keeping them clean is a...
Does anyone know if a very small stirling engine is made? I need to dissipate 800W of heat from a surface 5mm square and need to keep the stirling engine small (as in very small) Can any of you point me to something that would fit the application?
hey guys, in echo with some other posts on other topics... I searched and didn't find anything on this, so I'll post about it
I'm looking for a good book that will allow me to understand the fundamentals of aircraft design without going thru all the mumbo-jumbo of deriving equations from flow...
Does anyone have experience in treating the wastewater generated by a 2-phase olive oil extraction process? I haven't been able to find reliable data on the net regarding the strength of the wastewater or the complexity of the molecules in it. (including the COD and BOD values contained...
hey ppl
I have a pet project designing a surface effect craft, I hope to eventually make it a class III but for now it will be a class II only. And I have a few questions
I've been considering using rotary engines on it to get some extra reliability (its between that and diesels), this engine...
Hey everyone, I'm working on a project in Paso Robles california and we are trying to install a custom cush facility for olive oil and trying to make it as environmentally friendly as possible, we will have solar cells set up with feedback to the utility to counteract the cost of operating the...
