· the first flash was so bright it immediately woke me up. · a)determine the flash frequency with the resistance value shown. They produce a large blast but almost no shrapnel. I thought somebody just shined a bright flash light in my face from inches away. · 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%). I was confused by these. why does n-butane have a higher flash point but a lower autoignition temperature? · hey guys, i would like to create a mixture out of two liquids with an ideal flash point of around 70ºf. · tapes of the planes hitting the wtc towers clearly show a flash of light just as the nose of the plane touches the side of the building. My take was that a led driven by a rectified dc power supply will not flicker (provided the rectification is sufficiently smoothed out). · the flash point of n-butane is -60 degree celsius while that of isobutane is -83 degree celcius. The liquids i have to work with are 200 proof (100%) isopropyl alcohol (2-propanol) and aliphatic hydrocarbon mixture (aka hydrotreated petroleum distillates). 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. 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. The aromatic content of jp-5 might vary from less than 2. 5% to greater than 22% by volume. · i was in disagreement with my dad about this and hoped that someone could provide a definitive answer. · the size a vapor-liquid separator drum (or knock-out pot, or flash drum, or compressor suction drum) should be dictated by the anticipated flow rate of vapor and liquid from the drum. · the flash is just as bright as sunlight at daytime. · stun grenades, or flash bang grenades, operate on this principle. The room (kitchen) is in the second floor and is in connection to the living room. B) make a sketch of the voltage across the capacitor in such a circuit, showing several periods. Whilst he texted me this, taken from a manufacturers. To me, it looked like an electrical spark or strobe light coming from closer to the ground level. The second flash 5 seconds later, i was fully awake and sitting up and saw the reflection of it off the wall. Four views of the second strike, and the one and only film capture of the first strike show this flash. What im looking for is … The following sizing methodology is based on … The conspiracy guy suggested it was an incendiary device to make sure that the fuel ignited upon impact.
