around 15 mill for a crap small used one

limestone is used to reduce the phosphurus

Diesel fuel is used in diesel engines as a partial lubricant. It also has a high flash point due the fact that diesel engines ignite the fuel by compression rather than spark. A gasoline engine on the other hand fires the fuel by spark and the fuel has a lower flash point. Gasoline has no lubricating qualities whatsoever. Diesel engines are designed to run on diesel fuel and the use of gasoline in a diesel engine will destroy it. Gasoline engines on the other hand will not even run on diesel but no damage will be done to the engine. You will however have to drain the fuel tank and flush out the fuel lines.

Dear Sir Kindly suggest which book i have to refer for cold storage design or could supply some calculation guide book for the same mkjain 09910484067 i think u can refer to refrigeration and air conditioning by wilbert f.stoeker

on buses for brakes and in engineerring

mahit nahi

Yes

for ADNOC New HQ it's 10 fps (3 m/s ) , but usually in all other projects it between 2.5 fps- 3 fps

thanks

i dont know this nswer

A y pipe simply merges the two exhaust flows into a single tailpipe. The H refers to a piece of pipe installed between the two and before the y to equalize the flow in the two before they become one. No real horsepower gain to be made there.

The ejectors are used to maintain a system vacuum in the upstream (Example maintaining the vacuum column pressure) whereas eductor's main objective is to take out the volume of any fluid out of the system by maintaining a system pressure in the upstream.
example:
1. The eductors are used to remove the air 4 times the volume of the vessel per hour for the vessel entry jobs. We use compressed air as a motive fluid.
2. The water jet eductors are used to suck the muddy water, or a oily water from the storm water channel or a pit (an alternative for a de-watering pump). Here the motive fluid is high pressure water.
Hence the Eductors can be used to transfer a considerable volume of fluid from low pressure to high pressure with high compression ratio than ejectors. whereas the ejectors just suck the excess volume of the system and maintains the system pressure accurately.
The difference is with respect to their function and not with respect with their motive fluid. The diameter of the ejector's throat is lesser than the eductor.

Schedule 160 is thicker than 80

It's a little difficult to say out of context. It could be someone who repairs and maintains centrifuges, or it could be a fancy way of referring to someone who operates a centrifuge. If it's the latter, on the lab status scale it's about a half-step up the ladder from "bottle washer".

you can use a rubber connector with two "O"ring which are usually attached to the rubber. so you take rubber connection and slip it on the P tighting it and then do the same with the other side should work cost about $ 2.50

in a delta configuration the current is split between the phases, as opposed to a wye configuration where the current will be equal on all phases.

and vice versa for voltage.

put it in manual shift, manual clutch (shift key) using q key, put a powerful, rwd car (i.e burnside race) put it in 1st gear, hold clutch, floor the gas, let go of clutch

Common air conditioning rating is giving in BTU/hr. You can converted the rating BTU/hr to kW by multiply BTU/hr with 0.0002931 kW/BTU.

You can also estimate the cooling capacity from energy supply, generally COP for air cool air conditioning is 3.5 kWcooling/kWelectricity

arc welding such as SMAW (stick), GMAW (mig). Some cast metals may be brazed for certain applications.

The actual properties of the Cast metal will be needed for the type of electrode and/or process.

It is used to measure the rate of flow of liquid & glasses

That depends on fiber content, fiber orientation, fiber type. etc.

If you are talking standard wood pulp based paper, probably around 300,000 psi is good to use (2 GPa) but only as a ball park estimate

Hard to believe there are people so ignorant that this question was even asked! A "low profile" air conditioner is one that takes up a smaller amount of window space, as compared with "traditional" air conditioners. It is best on smaller windows, or where you want to maximize the view out of a regular window. Do a search of "LG GL6000ER" for an example.

Ignoring the classic joke that says you look out through the screen door, there are a number of ways of "seeing" outside.

Some submarines (especially small submersibles, research subs, and "tourist subs") do have glass windows.

Most submarines do not. They use other means.

A. On the surface, they have periscope (either direct sight or fiber optic). They have navigational radar. They have direct vision from the bridge of the sub (if it is fully surfaced and not simply at periscope depth).

B. Underwater, they have active sonar and passive sonar. Active sonar is like what bats use to echo locate what is in front of them. Passive Sonar is like using sound to figure out what is coming your way (like using your ears to safely walk around town with your eyes covered). Another primary method is Inertial Navigation. Using inertial navigation equipment tells you how fast you are going and in what direction. As long as you know where you start from, combined with good ocean charts, you know what is in front of you, above you, below you, behind you, and on each side of you. Fathometers (a lot like active sonar) can tell you how far you are above the bottom of the ocean, while pitot tubes can tell you how fast you are moving and how deep you are.

Combining all of these different sensors can be quite powerful. Much more powerful than looking out through a big glass window... you would not be able to see very much anyway.

Well first of all use the red and the black to connecty to the battery and then get a motion toy get the wires from there take out black and red then add your own plug it in where the origanals wore hopok up a larger battery or power source and walla technically a supe inovention! This is one of the smallest and simplest autonomous ones I have found yet, thanks to FriPilot http://members.tripod.com/robomaniac_2001/id120.htm Otherwise, I have had pretty good luck with buying small remote control cars at the dollar store (or the stuff my nephews throw away) and taking them apart to reconfigure the motors into what I want, but that ends up with wires connecting the robot to the controller. Some of the people I work with have pieced together radio control cars and other parts to get radio control robots. If you prefer robot kits, some hobby stores sell a few inexpensive ones that are sometimes configurable like these http://www.kitsusa.net/phpstore/html/Robot-Kits---Non-Soldering-1-1.html Otherwise some of the less expensive construction kits like Lego or K-NEX or Construx or a few others have motors and gears in the kits. If you have a larger budget, Lego Mindstorms, Bioloid and several others are more advanced kits that are programmable and autonomous. Some important terms to keep in mind are: operator controlled - the robot has motors in it, maybe some electronics, it doesn't move until you push a button or lever on the controller. remote control - usually connects the robot to the controller by a wire, you can usually keep the batteries in the controller to make the robot lighter. radio control - the controller is a transmitter, the robot has a receiver on it, both need batteries or some other power suppy. autonomous - you set up the robot and hardwire it or program it to run sets of commands, when you set it down and turn it on it runs the commands. Usually requires programming knowledge (like BASIC, C language, Assembly, ForTran, COBOL or some others) and electronics knowledge (like soldering, power supply vs. load, Programmable Logic Arrays, Trans/ceivers, sensors, and many other options). But of course it is the most fun. sensory feedback - the robot can have switches, sensors or detectors on it that send information back to the controller (or its processor if it is autonomous). Might require a transmitter on the robot and a receiver in the controller (with some indicators to tell you what the robot is "sensing"). Anthropomorphism - "the attribution of uniquely human characteristics to non-human" things and critters. There is a ton of things that can go together to make a robot. If you learn how to fix toys, appliances and cars it definitely helps you figure out robots.

You use the tool for filing object that are rough. You can use it a t school in the subject DAT.

On the off chance that you are keen on doing help for individuals or assuming you are keen on friendly work, medication would be the most ideal choice. ... On the partner, the non medication has various subjects and you can do specialization in them like electrical, PC, mechanical, Structural, designing, and so forth

While the clinical stream will be more hypothetical requesting that you create aptitude in the subtleties, the non-clinical stream will sharpen your scientific abilities. Be that as it may, once more, both offer plentiful measure of between disciplinary layers inside each stream which leaves no deficiency of new, less customary choices.

A chain block is a device where a chain runs through an overhead steel pulley block and can be used to lift things and be locked into place. A very useful tool .
