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 is mach regarding speed?
That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.
Mach speed is how many miles?
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
What is the speed in mph in mach 0.8?
Mach 0.8 = about 593.2 mph
What is mach 4 speed?
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
What is the maximum speed of an Dassault Mirage III?
A Dassault Mirage III can go Mach 1.52 (1127.0115 mph) without a rocket, Mach 1.8 (1334.6188 mph) with a rocket at max speed.
What is the Mach of Airbus A380?
Maximum speed: Mach 0.96Operating speed: Mach 0.89
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.
Moving at 5 times speed of sound?
An object moving at least five times the speed of sound is moving at hypersonic speed. Hypersonic speed is a speed greater than Mach 5. Aircrafts that can attain this speed are the X-15 rocket planes and Shuttle orbiter.
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 next speed after mach?
Mach 2.
The ratio of speed of a body to the speed of sound is called?
the Mach number
What does Mach 25 mean?
Mach refers to the speed of sound, for example, mach 1, equals the speed of sound, mach 2, the speed of sound times 2. So, mach 25 would mean, 25 times the speed of sound.
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 is mach jet?
Mach is the coefficient of the speed of sound, so Mach 1 means you are travelling at 1 x the speed of sound.
What is mach regarding speed?
That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.
How fast is speed?
Answer Mach 12 Supersonic Speed usually refers to speed just above Mach 1, or as high as Mach 3. Hyper-speed is a higher range but there is no set definition.
