Mar 13, 2006 · The discussion centers on the mysterious flash of light observed during the 9/11 plane strikes on the World Trade Center. Some participants speculate that the flash could be an incendiary device meant to ignite fuel upon impact, while others dismiss this as absurd. A more widely accepted explanation suggests that the flash results from the aluminum nose of the …
Dec 31, 2022 · 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.
Aug 22, 2012 · The discussion centers on the differing thermal properties of n-butane and isobutane, specifically their autoignition temperatures and flash points. N-butane has a lower autoignition temperature of 288 degrees Celsius compared to isobutane's 460 degrees Celsius, despite having a higher flash point of -60 degrees Celsius versus isobutane's -83 degrees …
Aug 12, 2006 · The discussion focuses on the properties and chemical compositions of various jet fuels, specifically JP-5, JP-8, and JP-10, highlighting their hydrocarbon mixtures and energy content. JP-9 and JP-10 are noted for their high energy density and specialized applications in missile technology. The conversation also addresses the physical characteristics of these fuels, …
Aug 5, 2006 · 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 following sizing methodology is based on …
Sep 23, 2010 · 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.
Jun 7, 2006 · The discussion focuses on calculating the flash frequency of a blinking light circuit using a neon lamp. The circuit charges a capacitor until it reaches 75V, at which point the lamp discharges the capacitor, producing a flash of light. The time to charge the capacitor is calculated using the equation V = Vo (1 - e^-t/RC), resulting in a charging time of approximately 0.1145 …
Jan 29, 2015 · The discussion focuses on optimizing camera flash performance through the analysis of a circuit involving a light bulb and a charged capacitor. The governing differential equation derived indicates how current develops in the circuit, with the current equation given as i (t) = Q/RC*e^ (-t/RC). For a desired quick discharge time of 0.01 seconds, calculations suggest a …
Jun 7, 2012 · To achieve a target flash point of around 70ºF for a mixture of isopropyl alcohol and aliphatic hydrocarbons, a precise calculation based on thermodynamics is necessary. Adding water to the alcohol can increase its flash point, with a suggested ratio of 70% water to 30% alcohol potentially raising the flash point significantly. The solubility of the mixture is crucial, as a two …
Jul 8, 2009 · A couple experienced a brief flash of white light while lying in bed, prompting speculation about its origin. They ruled out common explanations like static electricity or reflections, leading to discussions about possible scientific phenomena such as high-energy particles or spontaneous fusion. The girlfriend's belief in ghosts added a layer of concern, while the …
