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 0.8 = about 593.2 mph
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.
Maximum speed: Mach 0.96Operating speed: Mach 0.89
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.
340.29 m/s
the Mach number
The "Mach number" is the speed of the aircraft as a percentage of the speed of sound. So an aircraft going at Mach 0.74 is traveling at 74% of the speed of sound. (Mach 0.74 is a typical airliner speed.)
Mach 2.
No, Mach is a unit of speed used to measure an object's speed relative to the speed of sound in the medium through which it is traveling. For example, Mach 1 is the speed of sound.
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.
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 is the coefficient of the speed of sound, so Mach 1 means you are travelling at 1 x the speed of sound.
That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.
Answer Mach 12 Supersonic Speed usually refers to speed just above Mach 1, or as high as Mach 3. Hyper-speed is a higher range but there is no set definition.
