The Mach number of an object travelling through a fluid is its speed relative to the speed of sound travelling through the same medium. So an aircraft flying at Mach 1 at sea level would be travelling faster than an aircraft flying at Mach 1 at a high altitude (where the air is thinner and sound travels slower).
An object travelling at Mach 2 is travelling twice as fast as an object travelling through the same fluid under the same conditions (temperature and pressure).
BUT
In common usage, Mach 1 is the speed of sound in air, at sea level and 20 deg C.
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
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.
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
Mach 1 means the speed of sound. The speed of sound is 343meters per second, 1,126ft/sec or 768mph.
Match1? No clue. But you are probably referring to MACH 1, which is the speed of sound in air, roughly 340 m/s depending on air temperature. Mach 2 would be twice the speed of sound, mach 3 three times, etc.
Frantisek Mach is 6' 1 1/2".
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
If it is civil , its mach 1.- mach 2 ,name is Concorde & in defence they go beyond mach 2
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.
Mahha GoGoGo - 1967 Mach Five vs- Mach Five Part 2 1-23 was released on: USA: 1 December 1967
mach 1 = the speed of sound mach 2 is twice the speed of sound and that's how fast Concorde could travel, well, mach 2.3
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.
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
Wakusei robo Dangard A - 1977 Down from Mach 2 1-2 was released on: USA: 1980
Mach refers to the speed of sound, for example, mach 1, equals the speed of sound, mach 2, the speed of sound times 2. So, mach 25 would mean, 25 times the speed of sound.
Mach is a measure of speed based on the speed of sound at sea level. Mach 1 = 642 MPH . Mach 2 = 2 x 642 MPH or 1284 MPH.
Maybe you mean Mach 1 - which is the speed of sound. Mach 2 is twice the speed of sound, and so on ...
