- Jet Fuel, JP-5, JP-8 DFM: Properties, Chemical Composition . . .
JP-5 is a high-flash-point jet fuel developed by the Navy JP-5 is a specifically refined type of kerosene consisting of C9-C16 paraffins (53%), cycloparaffins (31%), aromatics (16%), and olefins (0 5%) The aromatic content of JP-5 might vary from less than 2 5% to greater than 22% by volume
- Unexplained bright flash of light inside house - Physics Forums
The first flash was so bright it immediately woke me up I thought somebody just shined a bright flash light in my face from inches away The second flash 5 seconds later, I was fully awake and sitting up and saw the reflection of it off the wall To me, it looked like an electrical spark or strobe light coming from closer to the ground level
- How to calculate flash point of mixture? • Physics Forums
Hi, a precise calculation, based in thermodynamics, is quite involved However, if you Google something like "Effect of Additives on the Flash Point of Flammable Liquid" you will find that you can begin by adding water to the alcohol to raise its flash point (for example, a mixture of 7 water 3 methanol seems to raise the flash point by 25 degrees C) You would then add this mixture to the
- Strange white flash in a dark room - II - Physics Forums
The flash is just as bright as sunlight at daytime The room (kitchen) is in the second floor and is in connection to the living room The room has a new kitchen now, but when it happened this summer, the old kitchen was completely removed, all lights were removed and the fuses in the fuse box were taken out
- Why N-Butane Isobutane Have Different Autoignition Flash Points
The flash point of n-butane is -60 degree Celsius while that of isobutane is -83 degree Celcius I was confused by these Why does n-butane have a higher flash point but a lower autoignition temperature?
- Debunking the Myth: Do LED Lights Flicker? Get the Definitive Answer . . .
I was in disagreement with my dad about this and hoped that someone could provide a definitive answer My take was that a LED driven by a rectified DC power supply will not flicker (provided the rectification is sufficiently smoothed out) Whilst he texted me this, taken from a manufacturers
- How Does a Grenades Shockwave Cause Fatal Injuries?
Stun grenades, or "flash bang" grenades, operate on this principle They produce a large blast but almost no shrapnel The noise and brightness of the flash are very disorienting, and the shock wave can actually knock a person down, but the chances of being killed by one, even at close proximity, are very slim
- Relativity of Simultaneity and lightening • Physics Forums
How would one be able to see a simultaneous flash but measure a non-simultaneous strike? 2 Why does the assistant share the same frame of reference with 'me'? Is it because of the equation x = x' +vt where v (assistant w r t 'me') = 0 and therefore x = x'? (Where x is 'my' frame and x' is the assistant's frame)
