Meaning Of Iso: Fill & Download for Free

ISO is the short form for International standardization organization.It was established on 26th February 1947 at Geneva, Switzerland.Basic function at that time was to harmonize different standards from varied disciplines.Initially only product standards were harmonized.In 1987, management standards ( such as ISO 9001,ISO 14001 etc) were also brought to the agenda and the name was changed to International organization for standardization.So logically the short form should be IOS but by then the acronym ISO was quite popular and had become a brand name. Therefore, it was maintained as ISO only.So even though the name has been transformed, the body is still officially known as ISO and all the standards are prefixed with the alphabets ISO.Hope you are able to get the concept.Thank you for this A2AHappy to help you.

Short answer: it could, but no one does it.Long answer: here we go….There are a couple of things that make a good chemical rocket fuel. In particular, the effective exhaust velocity, the velocity the escaping molecules would have in ideal conditions, is [math]v=√3kT/m[/math], where v is the effective exhaust velocity, k is the Boltzmann constant, T is the temperature, and m is the average molecular mass of the exhaust. It is important because it determines the efficiency of the rocket, or the specific impulse, which is just v / g0 (standard Earth gravitational acceleration).Any true gasoline rocket these days would almost certainly use highly refined gasoline, with all the sulfur and the more volatile fractions (like pentane and hexane) removed. As a result, we can approximate this gasoline (which would still run in your car!) as 2,2,3-trimethylpentane. This is known as the “octane” in high octane fuel, and it has a chemical formula of C8H18. The result of complete combustion of iso-octane in oxygen (as would be the case in a modern gasoline rocket) is 8 CO2 molecules (with a molecular mass of 7.308*10^-26 kg per molecule) and 9 H20 molecules (with a molecular mass of 2.989*10^-26 kg per molecule). We use a weighted average on those numbers and we get an average molecular mass of 5.021*10^-26 kg per molecule, so now we have m.The somewhat harder part is finding out what temperature the gasoline combustion products are. Luckily, it’s easy to find out the enthalpy of combustion (how much heat is given off) of iso-octane, and that number is -5640000 J per mole of iso-octane (negative means energy is released). Because molecular motion is the same across all molecules of the same temperature, we can assume that all the reaction products are at the same temperature. Dividing that number by Avogadro’s number gives us -9.366*10^-19 J per molecule of iso-octane burned in oxygen. Using the adiabatic flame temperature and dispersing the heat into the products, we get a temperature (starting at room temperature) of 2,771 K. Now we have T.Do the math, and the answer is clear: gasoline is far less effective as a rocket fuel than RP-1. In fact, gasoline is only half as efficient as RP-1. And that’s why they don’t use it.

ISO stands for International​ Organization​ For standardization​Many people thinks that ISO stands for International standardization​ for Organization.Even the name of the organization is standardized. The name, "ISO" is not an acronym but was derived from the Greek word "isos" meaning "equal". (The relation to standards is that if two objects meet the same standard, they should be equal.) This name eliminates any confusion that could result from the translation of "International Organization For Standardization" into different languages which would lead to different acronyms.
