That's 1100 f/s or 750 mph. PDQ.

Hi,
That does look cool, but it kinda sux without the sound in the video.

Bye!

The speed of sound is 331.46 m/s which is 1193.256 km/h, or 741.4549 mph. To everyone on the planet except engineers 750 mph is close enough

You're right, I wish I could find a copy of that with sound! They say the shockwaves you see are the sonic booms! cool!

Yes, yes... That's all fine and good 95mustanggt, but a real engineer would note that aircraft measure their velocity in nautical miles per hour "knots", not kilometers per hour, meters per second, or standard miles per hour.

In this case, the speed of sound would be 644.306692541 knots give or take a few millionths, or 644.31 when significant digits are used for the conversion from m/s.

Smartass.

[Tom351]

And an even realer engineer would note that the speed of sound changes depending upon what altitude (or air pressure) it is measured at.

The most real-est (if that is a word ) would note that the velocity of speed varies with the density of the medium at which the sound wave propigates.

Although Aircraft do measure speed in knots, I would prefer to use International units and go with m/s, after all the speed of sound is really just a measure of the velocity of an energy wave.

Boy, tough crowd

[Tom351]

And supersonic or close to it aircraft just use Mach number, so to obtain the highest level of realness possible, I say speed of sound = Mach 1.00 regardless of regardless of where and through what it travels.

Only stangers would have this discussion.
Ricers would be talking about wing aerodynamics.

Ya, if I add this cool japanese sticker I'll gain like 2000 lbs of thrust! And if I add a couple more wings, I'll be way faster too!

LOL,

Good one Tom!

Thanks 95

Everybody knows that the car with the largest wing is the fastest right?

You guy's kill me!
LMAO

[Rev]

Scientists might measure f/s, m/s, km/s, or light-years. LOL.

Rev

[Rev]

Should have said light-years/time unit.

Rev

[Unit 5302]

Isn't the speed of sound measured at mean sea level?

Anyway, if you wanted it in lightyears/time then your answer would be about 3.51315343847 x 10^ -14 lightyears/hour (measured at sea level), hehe.

Wow that looks a lot slower now doesn't it?

Both of you (95mustanggt, Tom351) do; however, raise interesting points about the speed of sound increasing and decreasing with altitude or the density of the mass it is travelling through.

I would submit the argument that the speed of sound as far as the sceintific communtity is concerned with rating an aircraft's top speed in the Mach designation is based on the speed of sound at mean sea level. Mostly that is because an aircrafts top speed, especially jet aircraft like, say, an F-15E, is obtained at high altitudes where researcher's are unable to accurately predict the changing pressure.

Besides, an aircraft rated at a certain Mach number, say the F-15E at Mach 2.65, is given it's rating at an altitude of about 56,000ft. Does that mean an aircraft that can do Mach 2.65 at 57,000ft is actually faster as far as the military is concerned? No. The rating has to be a constant rating, otherwise the Mach number given to an aircraft would be inaccurate based on a comparative factor when tracking it.

In conclusion, I'd say based on my theory, the Mach number is like an hp number. It's dependant on a conversion formula from another number like torque, in this case, a different designated velocity factor, such as m/s or knot's.

Hehehe, I love this **** !

[Rev]

Now that does sound exponentially slow doesn't it? LOL.

Huh?
You guys are just showing off

All I gotta say is it looks pretty d@mn fast to me hehe.

I cant argue with that unit5302.
