    Insulation Vacuum
AI Thread Summary
Vacuum insulation at 1 bar is not a true vacuum, as it represents atmospheric pressure. There is no specific formula to calculate the insulation properties at this pressure. Heat transfer calculations can be made based on convection, conduction, and radiation, but these depend heavily on the specific geometry and materials involved. The discussion clarifies that the original query about insulation does not pertain to vacuum insulated panels. Understanding insulation effectiveness requires consideration of various factors beyond just pressure.

I would like to know if there is a formula or a way to determine the amount of insulation a vacuum of 1 bar can produce. please note I am not talking about vacuum insulated panels.
 
Physics news on Phys.org
insulation to what ?
heat ? electrical ionisation something else ??

cheers

1 Bar is the atmospheric pressure, i.e. it is not a vacuum at all.

But regardless of the pressure: no there is no formula. It is of course perfectly possible to calculate the heat transfer due to convection, conduction and radiation; but all of these will depend on the geometry and the materials used.
 

Thread 'Mechanism of Energy Conservation in Zero-Amplitude Sum of EM Waveforms'

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
