What happens to Critical Mach number with altitude?
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
How fast is Mach 0.85?
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
What speed is 0.72 Mach?
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.
What are airplane mach numbers?
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.
What is 9 Mach compared with mph?
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.
The ratio of speed of a body to the speed of sound is called?
the Mach number
What happens to Critical Mach number with altitude?
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
What is the TM number for mach punch?
Mach Punch is not a TM so therefore it does not have a TM number.
What is Lower critical mach 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 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
What is critical mach number?
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.
What is a mach number in aeroplanes?
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.
How fast is Mach 1 Mach 2 Mach 3 Mach 4 etc to the fastest Mach level on record?
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.
What is faster then Mach 1?
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.
What is the Mach number at the throat section of a converging diverging nozzle?
The Mach number at the throat section of a converging-diverging nozzle is 1. This is where the flow reaches its sonic condition, known as choked flow.
What is mach in airplane testing?
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.)
What is the non-dimensional property that is 1 at the speed of sound?
The non-dimensional property that is 1 at the speed of sound is the Mach number. It is the ratio of an object's speed to the speed of sound in the medium it is traveling through. A Mach number of 1 means the object is traveling at the speed of sound.
