Thank you xez for all the input. The method we currently employ to determine power handling does take many of these things into consideration. Particularly derating factors, which currently rely on VSWR, altitude and temp. Upon closer inspection of precedents in Excel, it seems one the main...

We actually design and produce coaxial cables. I'm updating our in house power handling calculator (Excel based), as it is currently producing innaccurate results. The current equation used for it doesn't seem to synch up with other partial equations I've found, nor depend on enough...

Thank you for you responses. Summary of Below: I need an equation for the power handling of a microwave coaxial cable instead of the thermal one I spoke of earlier. I am sorry for not clarifying earlier, as I myself was assigned to look for the vague equation I mentioned. By clarifying...

I'm in need of an equation that relates the loss of heat (in power) of a cable to ambient air to various parameters such as diameter, temperatures of air and cable, and all other variable that may play a role. My research online has produced some results, but I haven't quite found what I'm...

Given this set-up. Consider a bead of mass m that is free to move around a horizontal, circular ring of wire (the wire passes through a hole in the bead). You may neglect gravity in this problem (assume the experiment is being done in space, far away from anything else). The radius of the...
