It can be calculated at any altitude - including negative ones - eg under water.
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
Mach number is dependent on a number of factors. Factors such as air density or altitude will change the Mach number. At approximatively 45 000 ft Mach 0.85 =289.2361 m/s = 1041.25 km/h = 647.0028 mph
It depends on altitude and humidity Mach I is about 1,225 kilometers per hour.
Ernst Mach .
The Mach number for the speed of an object travelling through a particular medium is the ratio of the object's speed relative to the speed of sound through the same medium. The speed of sound through any medium depends on the nature and density of the medium and, as a result, so does the Mach number. In air, the Mach ratio is mostly dependent on temperature and humidity, less so on altitude. Generally, Mach 1 (in air, at standard sea level conditions, and at 15 deg C) is approx 760 mph. So Mach 0.85 would be approx 646 mph.

Mach 3.3 is about 2,512 mph depending on altitude.
no mach no is defined as ratio of local speed of aeroplane to speed of sound. As the altitude increases the True speed of aeroplane increases and speed of sound decreases because of reduction of ambient temperature Hence the value of their ratio should increase at an increasing rate with increase in altitude. Keeping the Mach No constant say, 2 means reduction of speed to a large extent so as to maintain constant Mach No. Therefore same Mach no the aeroplane at higher altitude is flying slower
no. it's top speed was calculated to only be mach 3.5
MACH NUMBER can be calculated by dividing the spped of an object by its local speed of soundTo convert it into metre multiply it with the speed of sound. For example, to convert 0.8 mach into metre , 0.8 with 343 gives 274.4 m/s.
More than Mach 2 at its premium altitude.
It depends on altitude and humidity Mach I is about 1,225 kilometers per hour.
the Mach number
That all depends on the altitude the mach speed is occurring at. Mach 1 is defined as the speed of sound which is a function of fluid density. In air at sea level and normal temperature, 0.85 mach = ~647 mph 0.85mach ~.(0.85*330)mph

The speed of sound through any medium depends on the nature and density of the medium and, as a result, so does the Mach number. In air, the Mach ratio is mostly dependent on temperature and humidity and, to a lesser extent, on altitude. Generally, Mach 1 (in air, at standard sea level conditions, and at 15 deg C) is approx 1223 kmph. So 3400 kmph would be approx 2.8 Mach. But 3400 kmph in water would be a very much lower Mach number.
