Mach 1 is the speed of sound about 760mph.
Mach 0.6 = 457 mi/h
The non-dimensional property that is 1 at the speed of sound is the Mach number. It is a dimensionless quantity that represents the speed of an object relative to the speed of sound in the medium through which the object is moving. At the speed of sound, the Mach number is equal to 1.
Mach 10 = 7,612.1 mph
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 per second is 230,281,663 feet per second.
In fluid dynamics, the Mach number) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. Mach 1 is equal to 340.29 m / s
mach 1 = 761.207 mph, so 761.207 * 0.791 = 602.115 mph
340.29 m/s
Mach 1.7 is equal to about 1294 mph.
750*0.82=615 mph By the way, 1 mach is the speed of sound, which is 750 mph
Mach 0.6 = 457 mi/h
The non-dimensional property that is 1 at the speed of sound is the Mach number. It is a dimensionless quantity that represents the speed of an object relative to the speed of sound in the medium through which the object is moving. At the speed of sound, the Mach number is equal to 1.
There is no finite answer to this, since the term Mach (the speed of sound through air or water) changes based on the temperature of the air itself. In 60 deg F air at sea level, Mach 1 is 761mph. In dry air at 68 deg F, mach 1 is 768 mph. Mach 1.4 is 1.4 x these speeds. Usually Mach speeds are used for objects travelling in air, but not always. Mach 1 in water is 4.3 times faster than air and Mach 1 in iron is 15 times faster than air.
Mach 10 = 7,612.1 mph
Frantisek Mach is 6' 1 1/2".
Mach is the coefficient of the speed of sound, so Mach 1 means you are travelling at 1 x the speed of sound.
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.
