is that any formula to calculate the speed of blowing capacitor when it is blown up?

Capacitor stored energy = 0.5 x C x V^2

If C1 and C2 have the same uF values, then the energy stored in the 500V cap is 100 times that of the 50V cap,

since 500^2 / 50^2 = 100

We will assume that the stored energy (of charge in capacitor) = kinetic energy of part (when it explodes).

The kinetic energy of the part = 0.5 x m x v^2 where v = velocity of part, and m = mass of part.
and the m is the same for both capacitors.

Then the velocity of the 500V capacitor is ten times that of the 50V capacitor,

since v(of 500 V cap)^2 /v(of 50V cap)^2 = 100, and then v(of 500V cap) = 10 x v(of 50V cap)

So look out.

when 5v capacitor being feed with 50 volt and another 5v being feed with 500 volt could be the result will be different speed?
if different, how to calculate the speed?

How fast? In my professional experience... it was $250,000 bucks back in '85.

The capacitors, and diodes, were faster than my ability to lunge 14 feet to the big Red Button that shut down the test station... The power supplies were at 69VDC.

I ought to note that caps are sort of boring, they just blow up.... Diodes... ahh... put them volts backwards and watch them immolate themselves like a pico-X-ray-Death-star with a pulse of white hot plasma.

Why do you want to blow up capacitors?
You can always use other types of explosive devices for whatever you want to do.
Even reversed capacitors can blow up, though they are slower in that.

Back when I was taking the entry "analog electronics" course, we'd waste our time by blowing up transistors.

Three leads... three holes in the AC outlet.

Or my first ever hacked power supply. I didn't need no stinking ON/OFF switch. Hmmm.... lots of clean up after the big caps blew up. I mean, I was at the He-Man-Can-Do-No-Wrong stage of my life... who could have expected that I'd wire them backwards, huh?

The caps were FASTER than I could reach down under the desk and yank the power cord..... big buggers were fast, I tell ya...

what????????$2500000 ???? what capacitor so expensive???????
 
Large capacitors look ferocious when they blow. even for some of the little guys. I heard/ seen aftermath of a 12 volt inline auto cap blow. The kid was installing one as new and starting the charging process he didn't get to finish. He was fine from working and duct under his hood when it went off.
