What else can I help you with?
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,
Who invented the mach number?
Ernst Mach .
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
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
A collection of aeroplanes?
The collective nouns for aeroplanes are a flight of aeroplanes or a squadron of aeroplanes.
Why are aeroplanes made in streamlined form?
Aeroplanes are built streamlined to increase their flight efficiency. A number of other reasons are involved, but this is the main reason.
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.
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.
