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
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.
Mach refers to the speed of sound. A plane that travels at Mach 2 means that it travels twice the speed of sound in air. The actual speed will vary a bit depending on the altitude.Mach number is a measure of relative speed. It is the speed of something relative to a medium, usually air, and divided by the speed of sound in that medium: : : is the Mach number : is the velocity of the object relative to the medium used and : is the velocity of sound in the medium Mach number is the number of times the speed of sound an object or a duct, or the fluid medium itself, move relative to each other. It is named afteran Austrian physicist Ernst Mach.
The speed of sound (and hence the Mach number) depends on the nature and density of the fluid through which the sound travels. Generally, though Mach 1 (in air, at sea level, and at 15 deg C) is approx 760 mph. So Mach 9 would be 6840 mph.

Mach Punch is not a TM so therefore it does not have a TM number.
Lower critical mach number may be defined as the highest subsonic mach number below which the entire flow over it is subsonic. vijayaprakaash

Mach No at throat = 1.0
Critical Mach Number, or Mcr, refers to the lowest Mach number that air going over and around an aircraft can reach the speed of sound. If an airplane goes over its Mcr, handling might be greatly affected.
The mach number is the speed of an aircraft, expressed as a fraction of the speed of sound in the atmospheric conditions in which the aircraft is flying. An aircraft flying at mach 1 is flying at 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.
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 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.
Indicated Mach number which is corrected for instrument and position errors equals True Mach Number Instrument errors are errors due to manufacturing or design defects that all instruments have to some small degree. Position error is due to the position of the pitot and static ports on the aircraft getting disturbed air pressure from some part of the aircraft's structure.
