What Mach means?
A Mach number is the ratio of an object’s speed in a given medium to the speed of sound in that medium. Mach 1, then, is the speed of sound, around 761 mph at sea level on a standard day. The term is also used as a metaphor for high speeds more generally.
How is Mach calculated?
The Mach number is a dimensionless quantity. Mathematically, the Mach number equation can be written as: M = v / c , such that v is the speed of the object and c is the speed of sound.
How do you calculate Mach?
What’s the fastest Mach speed?
The Fastest Fighter Jet Ever It reached record top speed of Mach 6.72 or 4,520 mph, which is more than five times the speed of sound. The X-125 was an experimental hypersonic rocket-powered aircraft developed in the 1960’s and still holds the record for the highest speed ever recorded by a crewed, powered aircraft.
How fast is the fastest jet?
The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner.
