- 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
Hey guys, I would like to create a mixture out of two liquids with an ideal flash point of around 70ºF The liquids I have to work with are 200 proof (100%) isopropyl alcohol (2-propanol) and aliphatic hydrocarbon mixture (aka hydrotreated petroleum distillates) What I'm looking for is the
- 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
- Optimizing Camera Flash Performance: The Role of RC Circuits
Homework Statement Consider the following circuit in a camera flash where a light bulb is in series with a charged capacitor: a) Derive, but do not solve, the governing differential equation for the circuit (Hint: treat the resistor and the light bulb as a single resistance ) b) Assume
- Calculating Flash Frequency in a Simple Blinking Light Circuit with . . .
a)Determine the flash frequency with the resistance value shown b) Make a sketch of the voltage across the capacitor in such a circuit, showing several periods
- Flash Point of Petrol Diesel: Pressure Self Ignition
Flash point temperature of petrol is lesser than that of diesel at the same pressure Does this mean, if I take petrol and diesel as liquids in separate containers and heat them, rapid vapourisation (rapid enough to sustain a combustion) of petrol occurs at a lower temperature (fire point) than that of diesel?
- 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?
- Flash Light at the Speed of Light Question - Physics Forums
These are the kinds of thought experiments which led Einstein to develop special relativity, which includes the fact that no one can go at the speed of light
