The Bell X-1
When something is traveling at the speed of sound, 343 m/s, it is said to be traveling at mach 1. When traveling at twice the speed of sound it is traveling at mach 2 and so on. Wikipedia.org, 'The World's Encyclopedia' has an entire article on Mack Number. Refer to the related link in the Related Links section below.
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
Ernst Mach .
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
That is a great question. I have no idea.
They can swim at mach 5 speeds
conventional jet engines (using a compressor) will operate at speeds up to slightly less than Mach 1using an afterburner a conventional jet engine can operate at speeds slightly above Mach 3ramjet engines will operate at speeds up to about Mach 5scramjet engines can operate at speeds well above Mach 6However the maximum speed of of an actual airplane is usually less than the capability of the engines it uses.
Scramjets can reach speeds up to Mach 15 (15 times the speed of sound) which is around 11,500 mph (18,500 km/h). They are designed to operate efficiently at hypersonic speeds, typically around Mach 5 or higher.
Speeds faster than Mach 1 are measured in multiples of Mach, such as Mach 2 (twice the speed of sound), Mach 3 (three times), and so on. Each Mach number represents the speed of an object in relation to the speed of sound.
The Mustang Mach I will reach speeds in excess of 105.5-mph. The Mach I will accelerate to 105-mph in 13.13-seconds. It is faster than the SS Camaro.
At high speeds and altitudes
speeds lower than the speed of sound is known as the subsonic speed. speeds greater than the speed of sound is supersonic (mach 1) and speeds that are many times above the speed of sound (above mach 0) are known as hypersonic sounds.
Due to mach speeds being the percentage of the speed of sound and the speed of sound changing with air density and temperature the answer varies but mach .95 at 30,000ft is 645.05 mph
Humans are not capable of running that fast, no, but they can travel that fast using a vehicle. The current air speed record is Mach 6.7.
Supersonic speed is defined as speeds greater than the speed of sound, which is approximately 343 meters per second (767 mph) at sea level. Aircraft flying at supersonic speeds typically travel at speeds ranging from Mach 1 to Mach 5, or roughly 343 meters per second to 1716 meters per second.
