3] that the expected uncertainties (two standard deviations) in speed of sound
, for a typical pipeline gas operating below 1,480 psig, are:
Augmenting the output of the Coriolis meter with a speed of sound
measurement provides a new approach to improved density measurement for aerated fluids in two ways.
It may also explain seismic shocks that have been observed to travel faster than the speed of sound
By the time the energy reached the tail tip, that dino "whip" cracked faster than 1,200 km (760 mi) per hour--the speed of sound
Larson continued, "Within 10 seconds of launch, the rocket will be traveling five-times the speed of sound
-- Mach 5 -- and on it's way into space.
The plane, dubbed HyperSoar, could attian a hypersonic top speed of 3 kilometers per second, or Mach 10--10 times the speed of sound
, it could transport freight and people, strike enemy targets, or help propel payloads into space, in most uses, it would not only go places faster but would also haul more load per kilogram of aircraft than existing planes or rockets do, says Preston H.
He hopes to see it beat his record--and maybe even zoom past the speed of sound
(about 750 mph or 1,200 kph).
The Hyper-X launch vehicle uses a modified first stage rocket motor, originally designed and flight-proven aboard Orbital's Pegasus(R) space launch vehicle, to accelerate NASA's X-43A air-breathing scramjet to seven times the speed of sound
Because the speed of material orbiting near the core is at most only a few times higher than the speed of sound
, acoustic waves could push gas and dust around with relative ease, Elmegreen and his colleagues note.
By analyzing the speed of sound
through the ocean over time, the scientists will be able to determine if our planet is warming up.
Unlike CT and MRI, the TechniScan system also provides information about the bulk tissue properties, speed of sound
and attenuation of sound resulting in actual Quantitative Tissue Characterization(TM) (QTC).
The X-43 fired its experimental engine for about 10 seconds, cruising at speeds approaching 10 times the speed of sound
