what is the right way of checking the tension of the flat belts or V belts in drive mechanisms

Hi guys, what role does the pressure drop across a heat exchanger plays, why is it such an important perimeter in heat exchanger designs?

The way I see it is that high pressure drop will lead to high velocity at the exit of the heat exchanger, possibly causing erosion problems. Required flo

It's not that difficult to confuse the two. Besides the similar names, both were quarter-ton, four-wheel-drive replacements for the Jeep. The timelines for the two overlap, and both feature independent front and rear suspensions. But the differences between the two are substantial.

So le

There are many reasons to explain why some of the world's species have become endangered. Habitats have been lost to housing developments, food sources have become scarce due to overfishing, and some animals are simply hunted to extinction. Now, conservationists are saying that technology cr

Plasma arc cutting (PAC), or plasma cutting, is a process by which a vortex of pressurized gas is ionized to heat and melt electrically conductive materials. The PAC system's parts are configured to constrict and focus the vortex of ionized gas on an electrically conductive material so that the

I am getting ready to bid on some concrete work, and am in need of some advice on forming large walls. They will be supporting mining equipment, the largest of which is a primary crusher weighing 365 tons. The wall structures I have found for similar equipment have been roughly 25' high, 40' long, a

Wondering about you, man? How close is your platform to the epicenter? Are you still on it?

Hi anyone out there got a good method of making ones own lead screws

I have an old Emachine T1115I have reinstalled the hard drive numerous times and the more I do the slower it gets. The last time I did it it takes 45 min from the time you turn it on to get to the home page and load ever thing. I want to install service pack 2 and it took 6 hrs. now I went to my com

i have a 305 5L eng. I replaced the radiator and hose because it was leaking and overheating before. I replaced that and now it smokes now-WHITE SMOKE so i flushed raditor and no smoke now i only use water in radiator. When starting it needs gas to get it started and then it idles real irratic wit

If you have a panel this is rated for a 200% neutral does the feeder to it need 200% of neutral? I know it isn't a code requirement or anything just wondering what would be the point if the neutral isn't sized to carry it, the individual non-linear loads will combine on that neutral bus in the panel

A neural engineer from Case Western Reserve University is reviving paralyzed limbs with an electricity hack. It's a brilliant workaround for spinal cord injuries, and it may someday let paraplegics activate their legs just by pushing a button. It's not just a pipe

The Chikyu research vessel is already the world's deepest drill, probing nearly 23,000 feet beneath the ocean floor. But scientists hope to add another mile to the machine by 2013, allowing it to pierce Earth's mantle for the first time. PopSci has a look at how th

This is how the plane flown by 18-year-old Patrick Humphries looked after he crash-landed it in the middle of a busy highway. Humphries was uninjured and simply stepped out to halt traffic after his plane stopped spinning out of control. Apparently the single-engin

Hello Folks,

We have Diesel Engine generator which has been overrated,

Presently At the max the load on the engine is 20%, would you suggest any ways we can increase the load for the purpose of breakin, such as load banks used for testing the generators load testing, by doing so are we l

Why in everiday life when people speak about action they reffer to acts of violence, destruction, killings and stuff like that. Are we just a bunch of "neanderthals"? Further more one question remains: How do we change this?

Hello,

I am trying to source plastic films for a cut in place thermoforming application. The product that would be created will be used in a air to air plate heat exchanger. The thermal conductivity must be better than 0.2 W/mK (preferably above 1 W/mK). The material should be no thicker th

Hi

I am working on a ubiquitous computing project these days. Was wondering if anyone had heard of a commercial zigbee wifi hub? Or tried to make one themselves?

Cheers!
