We have a salt pulveriser to pulverise the crystal salt to fine powder.During this operation we find lot of fine dust generation resulting in accumulation of the dust on the surrounding areas.The room size is around 6 ft width ,15 ft long and 15 feet high with opening on top.The salt rate is 100 kg/

Can someone explain what the purpose of TTR (transformer turn ratio) testing is suppoed to catch? Why we test for it?

I am seeking information on heat recovery systems for multiple freezers in a dept. store setting. I am new at the whole topic but have been asked to look into it for someone even less computor savy than myself. The store has about 20 freezer type compressors.Air conditioning units are also evident s

I have a HP DV8000 laptop (8040us specifically I believe) with a 17" screen. About a month ago I took it out of the laptop case and started it up, I noticed a White stripe about 1 inch wide about 2 inches from the right side of the screen which ran vertically the entire length of the monitor. In thi

I often use chrome plated steel in creating junk sculptures. Items such as chrome wheel nuts, old sockets, chrome-vanadium spanners etc. I would like to know if the fumes from welding such items can be hazardous. I don't normally wear a respirator for ordinary steel welding (perhaps I should) but ar

Can anyone advise as to what shaft material is best in a low energy, low pressure centrifugal glycol circulating pump? I am leaning toward 4140. Any thoughts?

I am currently working on a project, and collecting data on Advanced Monitoring & Targeting (Energy Consumption ) along with Intelligent Motor Energy Controls.

I am a novice in this technology,any ideas, suggestions, or personal experience feedback

you could offer would be greatly apprecia

I have been given the glorious task of performing a cost reduction study on a current part that is made from stainless steel (303 and 440). I have been asked to reduce the cost by making it from carbon steel rather than stainless. I have already determined that there might not actually be a reduct

We are developing a sand blasting media engineered from recyclable plastic that will compete with 3 or 4 existing medias currently on the market. To help us position this product and help us have an understanding of the actual size of the market could someone assist us with the following 2 marke

I am trying to build a simple a stable 555 timer to switch a smallish dc motor off and on. In simulation it works. However, when I proto the board, everything works right, on/off interval is good, relay opens and closes.......................until I add the motor, then I get the magic smoke from th

Hi. I have been given a Dell Latitude to have a look at by a friend, because the backlight for the screen doesn't work. I am not sure whether this is due to the inverter or the backlight not working, and I don't have any way to test them. The laptop will turn on, and if a VGA cable is plugged in,

Hey all, i would like to ask what is the reason that cryogenic vessels do not use water for hydrostatic test, and uses air or inert gas for the test instead?

Thanks!

An internally connected Dyn11 transformer can be changed to either Dyn3 , Dyn5 , Dyn7 , Dyn9 or Dyn11 transformer , by doing external changes on both sides of the transformer . Verify the above mentioned statement....

I have an old philco/ford air conditioner Model AC505 8,000 btu that needs a dual capacitor. Compressor is fine but fan needs a boost by hand. one side of cap is rusted and starting to leak, markings are gone. It's one of the old quart size caps.

Most fan caps are 5uf but i don't know what

We have a Dell laptop with a stuck "A" key. We plugged in an external keyboard, but the A key on the laptop periodically (every few minutes) goes berserk and inserts a string of "AAAAAAAAAAA" until we jab the A key a zillion times to get it to stop.

Whilst we await the arrival of a replacem

hello, I am trying to do a model of a very old transformer and autotransformers using the Etap computer program and I need to know how to get the zero sequenze impedance to do some shortcircuit test. those are YYn transformer 7,5 MVa 67,56/0,575 Kv Z=7.5pu are there some Ieee book or som

Hi

We use this chip which is a 12 bit A/D converter on one of our circuit boards. We purchased a large quantity of these chips in 2007. Recently we have been experiencing random intermittent failures. Sometimes the chip fails at startup other times after a month. A few have failed in the f

The Copenhagen Wheel is a "green technology" project that emerged out of MIT's Senseable lab. http://senseable.mit.edu/copenhagenwheel/wheel.html Back in December, during the climate summit, they showcased the bike with the technology in the city of Copenhagen, who were actually one of the three spo
