Last night I was awoken by what seemed like an extremely bright flash of light I sat up and saw another bright flash of light just outside my bedroom that
- 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
- Flash Joule Heating (FJH) Method for treating process waste streams
I caught the tail end of a video about a new application for treating chemical or process waste, which is applied to 'red' mud or contaminated bauxite residue, but the person of interest mention recovering critical minerals from consumer electronics, as well as treating mine tailings and

- Find Capacitance for Camera Flash Unit - Physics Forums
Homework Statement The flash unit in a camera uses a special circuit to “step up” the V = 3 1 V from the batteries to V' = 300 V, which charges a capacitor The capacitor is then discharged through a flashlamp The discharge takes t = 12 μs, and the average power dissipated in the flashlamp is
- How to reduce tin? • Physics Forums
The discussion focuses on methods to reduce tin from scrap pewter, particularly exploring the use of ascorbic acid as a reducing agent There is uncertainty about ascorbic acid's effectiveness on tin compared to its action on copper and silver An alternative proposed is oxalic acid, which may drive the reaction through CO2 release, although its low solubility poses contamination risks The
- Why N-Butane Isobutane Have Different Autoignition Flash Points
