Comment on Does Mach speed change depending on the altitude?

Yes a fair amount. At ground is about 760mph at 40000 feet about 659.
Temp and humidity factor some as well.

Interesting. So orbital Mach is like what?
MrEff@lemmy.world 6 months ago
Technically it would reach an altitude where it would become null due to dividing by zero. You would eventually hit the vacuum of space where there is no speed of sound and any speed is faster than it.

Like a zillion.

So what’s Mach in outer space
XeroxCool@lemmy.world 6 months ago
That’s where speed is relative. But if you had to use a Mach number, it’s be at sea level or standard temp/pressure
