Why phosphor screen is used in night vision goggles?
In a night vision tube, the object of the tube is to convert incoming light particles (photons) to electrons. The electrons are then multiplied many times by the microchannel plate inside the tube. It is these multiplied electrons that are the output 'signal'. However, since your eye cannot see electrons, they are converted back to visible light by way of the phosphor screen which 'lights up' when energized by the electrons.

What is the education required to become an Illumination engineer?
Competitive candidates will have a minimum of a BS in Physics, Optical Engineering, or a similar discipline, and 5+ years of experience in illumination system design or optical engineering with experience related to illumination systems. Candidates should also have 2+ years of experience utilizing technical program management disciplines. Illumination projects require a strong CAD background, preferably utilizing a surface based modeler such as Rhinoceros® ("Rhino") or a solid modeler such as SolidWorks®. Experience with ASAP and ReflectorCAD, or other Monte-Carlo ray trace simulation programs and a solid understanding of different types of illumination systems are required. Candidates who have knowledge of ASAP preferred. (this is from a job search description)
What is the meaning consumable welding?
Consumable electrode welding contain the processes where the electrode acts as the filler material and the electrode that generates the arc. Because the electrode is also the filler material, the electrode 'burns' or is consumed, hence consumable electrode.
It depends on many parameters. Generally between 3 to 5 Tonnes per Hour.
What is vapour liquid equilibrium data?
when number of molecules into vapour state from liquid state is equal to number of molecules going from vapour to liquid equilibrium is said to have been established
What are verticals and horizontals in any industry?
Vertcals are industry specific focus groups that will be useful (a) to align the industry domain specifics and (b) to align with the clients belonging to this industry Horizontals are the specific capabilities or skills (technical and non-technical) that "span across" two or more industry verticals
Yes, it is magnesium sulfate heptahydrate, also known as Epsom salt.
What is difference between manufacturing plant and pilot plant?
A manufacturing plant basically manufactures a chemical on a mass scale however a pilot plant helps to develop the process on a small scale, before a manufacturing plant is built.

What is FM200 fire extinguishing gas?
Hi,
FM200 is a synthetic/chemical fire suppression gas and extinguishes a fire by removing the free radicals or heat elements from the fire triangle. (Oxygen, Heat and Fuel). The typical concentration of an FM200 system is normally between 7.9% to 8.5%.

If NaNH2 is dissolved in liquid ammonia it is an acid or a base?
Well ammonia is a weak base and and NaNH2 is a strong base, so overall, you've got a pretty strong base.
What is upstream and downstream system?
Upstream and downstream systems are business terms that apply to the production process. The search for and extraction of raw materials refers to upstream. When these materials are processed refers to the downstream.
i think it has to do with off grid electricity generation
Is fractional distillation a physical method?
Yes - fractional distillation is a physical method. It relies on differences in the physical properties of the components being distilled and left behind. In particular, it relies on the differeces in vapor pressures of the different components - or the fugacities if you want to get more involved in the actual thermodynamics.
What are factors affecting the reid vapor pressure of an oil?
The amount of light components in the oil affect the reid vapor vapor pressure. In petroleum products such as gasoline, the amount of butane in the gasoline blend has a strong affect on the Reid Vapor Pressure. To reduce RVP more stripping steam can be added to the product strippers. The fractionation in the debutanizer might also need to be adjusted to affect the RVP.
