How Loud Is a .270 Rifle?

generally any centrefire rifle is considerable louder than a shotgun, although the 10 gauge comes close. And as nearly everyone pointed out, firing a rifle without ear protection is guaranteed to cause permanent hearing damage, and fairly quickly at that. (So will a shotgun, but it might take longer). The .270 (and .280 for that matter) is every bit as loud as the .30-06, being the same size cartridge case and powder capacity. The danger to the eardrums from gunfire is a function of the velocity of the sound waves. Even one shot can be harmful, whereas the noise of auto racing, industrial machinery, or amplified music generally is dangerous only under conditions of prolonged exposure. The first time I fired an M-16, I thought the little 5.56mm could not be that loud, so I did not bother with earplugs. BIG mistake, anything moving at 3200fps has a painfully sharp sonic boom, in addition to the explosive blast of the powder being ignited. So like Mr. Adler tells the kids in shop class, do not screw around.

1. What is the 3-phase voltage in India? (used for example with industrial machinery)?

I would ask the company that is buying the machine. They can put you in touch with the Power supplier if necessary.

2. can you hang liquidtight from a 20' ceiling to a 4 square with knockouts in a commercial installation?

Article 350 of the NEC is for Liquidtight Flexible Metal Conduit. Article 350.30 deals with securing and supporting. Article 350.30 (A) LFMC shall be securely fastened in place within 12 inches of each box and supported and secured at intervals not to exceed 4 1/2 feet. The only provisions I can find for an exposed vertical riser of 20 feet is in Articles 342 and 344. IMC and Rigid Metal Conduit. But this is for industrial machinery. There are no exceptions with LFMC other than unsupported lengths not exceeding 6 feet for luminaires (light fixtures). I would say the application you are going to use is in violation of the code.

3. how can i find Industrial machinery in Germany?

What do you mean? Buying some? Looking on some? Which machinery?

4. What is an acoustic rating?

There are many number of acoustic ratings, which are often different depending on the guidelines provided in your country.Some common ratings in acoustics would be:Sound insulation/reduction - There are any number of ratings used in sound insulation, which are used to specify the reduction in sound pressure through a partition (such as a wall or floor). In the UK the figures used depend on the usage, but laboratory tested figures are specified as Rw (before construction) and on-site test values are noted as Dw (after construction). Other variations of the values are used for testing performance of partitions (such as DnT,w in hospitals, or DnT,wCtr in residences).The sound reduction provided by glazing is often given as Rw, while natural ventilators are often quoted as Dne,w.Noise Ratings - In the UK noise rating curves (called NR curves/ NC curves are used in USA) is often used to specify noise limits for industrial machinery, or other things that may have the majority of its energy in low frequency bands. See the image and link below from Engineering ToolBox for more information.NR - Noise Rating CurveI guess some other ratings could be used for reverberation times:T60 - The time taken for sound pressure level in a room to decrease by 60dB.More practical values used are the T20 and T30, which extrapolate the time taken to reduce by 20/30dB. It is rare that a full T60 is measured in normal spaces, as you would need a very loud source, or a highly reverberant space!Absorption coefficients - These values are used to provide information on the absorptive properties of a certain material. This allows for the prediction of reverberation times in a space that has not yet been built.Simple predictions can be made using classical formulae, and more complex calculations can be made using 3D modelling software and a number of algorithms. See below from my company Prism Acoustics:There are many, MANY more acoustic ratings, but hopefully some of these will give you somewhere to start!

5. OIL is not Just OIL ..... . . Do You Understand the True Values of Oil ? How would factories operate without?

I know this is difficult to believe, but factories and business operated long before the use of oil and electricity as an energy source. And if all the oil wells dried up tomorrow, business would go on. Prior to coal and oil, the U.S. economy was fueled by wood and water. Waterwheels ran industrial machinery. Wood was burned to produce steam. Wood was cheap and easy to harvest. BY the 1870s, however, most of the available forest had been cut down, and the country faced a wood famine. Everyone at the time was sure the country faced ruin. You need to quit worrying about the oil supply. For more than 50 years, people have been saying we will run out of oil one day. Do not you think that the oil companies with their trillions of dollars in assets are prepared for the future? Oil is still the cheapest energy source. When it runs out, we will go on to another energy source without missing a step. Here's a peek into the future. A company in S. Africa has developed roofing material that produces electricity. This material has the potential to make every home energy independent. If every existing home in the U.S. uses this roofing material, we would cut coal and oil usage by 40%. If this technology can be applied to film coatings like paint, every painted object has the potential to produce electricity.

Understand Industrial Machinery: an Introduction to Industrial Machinery
An Introduction to industrial machineryFive-Year Plans of Nepal generally strove to increase output and employment; develop the infrastructure; attain economic stability; promote industry, commerce, and international trade; establish administrative and public service institutions to support economic development; and also introduce labor-intensive production techniques to alleviate underemployment. The social goals of the plans were improving health and education as well as encouraging equitable income distribution. Although each plan had different development priorities, the allocation of resources did not always reflect these priorities. The first four plans concentrated on infrastructure-to make it possible to facilitate the movement of goods and services-and to increase the size of the market. Each of the five-year plans depended heavily on foreign assistance in the forms of grants and loans.Ringing in my ears. What's the cause? of industrial machineryHello, a little info from webmd.com,PreventionShare this:You may be able to prevent ringing in the ears if you: Limit or avoid exposure to loud noises, such as music, power tools, gunshots, and industrial machinery. Wear protective earplugs or earmuffs if you cannot avoid loud noises. Do not use wadded-up tissue or cotton balls. These do not protect adequately against loud noises, especially the more dangerous high frequencies, and they may become lodged in the ear canal. Be careful when using stereo headphones. If music is so loud that others can hear it clearly or you can't hear other sounds around you, the volume is too high. Cut back on or stop drinking alcohol and beverages containing caffeine. Do not smoke or use smokeless tobacco products. Nicotine use may cause tinnitus by reducing blood flow to the structures of the ear. For more information, see the topic Quitting Smoking. Exercise regularly. Exercise may prevent tinnitus because it improves blood flow to the structures of the ear. For more information, see the topic Fitness. Maintain a healthy weight. Tinnitus occurs more frequently in obese adults. For more information, see the topic Weight Management.Myths About Storage Container Auctions of industrial machineryIf you are looking to go for a storage auctions in your area then there are various important things that needs to be considered.
