That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.
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.
Mach is not an absolute speed but a relative speed. The Mach value of an object is the ratio of the speed fo the object travelling through a medium to the speed of sound travelling through the same medium. Now sound travels faster in denser mediums so the speed of sound in [dense]air at sea level is greater than the speed of sound at high altitude. So Mach 2 in the air at sea level is faster than Mach 2 at high altitude. But Mach 2 under water is very much faster. However, most people are ignorant about the proper meaning of Mach and assume that it is simply related to the speed of sound at sea level at normal temperature/pressure/humidity - approximately 760 miles per hour. In that case Mach 8 would be 6080 mph.
0,72 Mach is a subsonic speed. Mach number = speed of an object/speed of sound The speed of sound in dry air at 20 0C is 1 236 km/h.
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.
Mach 2.
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.
That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.
340.29 m/s
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
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
If it is civil , its mach 1.- mach 2 ,name is Concorde & in defence they go beyond mach 2
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.
Maybe you mean Mach 1 - which is the speed of sound. Mach 2 is twice the speed of sound, and so on ...
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.
