I'm just going to hazard a guess that you're talking about the altiplano area of the andes since you're that high and off the grid...
Have you thought about doing solar concentration for flash evaporation? There are a few companies out there that have good solar condenser and tracking systems...
This is a fluidized bed system, but the mixer is also mecanically turning paddles at all times that the CO2 is being injected so the gas is not the only thing causing mixing. This is not a design application, the mixer as it exists is what I'm stuck with. I'll give the enthalpy of the liquid vs...
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...
I'm rinsing and neutralizing with citric acid and finally an RO rinse after, so taste is not an issue.
This is an industrial sized process, for the size of things I'm cleaning I can't use ethanol because it becomes a hazmat problem and I don't have a way to dispose of the effluent after I'm...
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...
I was assuming that internal ice was the only problem, I still say: heat the unit somehow, is the alloy of the perforated pipe a magnetic metal that you could heat with induction? that way you don't have to have to run wires in there or rely on inefficient heat transfer from the outside.
I understand that deflection WILL happen, all I need to show is that the weight of the water will not exceed a fourth of the yield strength of the beams involved.
I basically need to know what the yield strength of different cross sections and materials are for the size of these beams. I can...
If I understand what you're talking about correctly, there is a very well known and very deadly condition that is similar to what you're talking about in aircraft (and cars) called carburetor icing. humid air drawn into the carb is cooled by the vaporization of the fuel and water condenses and...
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'm still waiting for the diesel-electric parallel hybrid. I'm surprised they haven't come out yet. So long as series hybrids can have a realistic range under electrical power (100 or so miles) I see no fault with the series hybrid configuration.
I like the idea of the series hybrid, a while...
The beauty of having a series hybrid is that engine load doesn't necesarily have to have anything to do with actual vehicle speed. Yes you have vastly different loads at different speeds, but when idling and/or decelerating, the power production from the engine can be re-routed to charging...
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...
Correct me if the assumption is incorrect... But I would assume that natural convection would not play a hugely significant role in the loss of heat to the atmosphere, the boundary layer between the water and the air would be the transfer point of heat, and because evaporation cools the air in...
Never over-estimate the stupidity of people, and it takes a college graduate to make truely stupid decisions.
This whole discussion has unfortunately reduced my faith in wind power by a lot and is starting to remind me of the whole push for bioethanol from corn. The vast majority of people...
I agree with removing the skins with a screen. In my experience, a wedgewire screen with beveled upstream edges is very resistant to clogging. Clogged valves are a major pain to clean and represent a potential weak link.
Strain the peels out and transport them via their own dedicated conveyor...
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...
