What is mawk 1, 2, and 3? How much speed is each mawk?

Question

Like jets going mawk I, II, or III. Is each mawk 1,000 MPH or something?

Answer 1

"Mach," after Ernst Mach.  Not "mawk."

http://en.wikipedia.org/wiki/Ernst_Mach

And it isn't a fixed speed.  It depends on the speed of sound in the medium.  I the case of air, it varies by the air pressure and temperature.  So it depends on altitude and the weather.

http://en.wikipedia.org/wiki/Mach_number

Mach 1 is the speed of sound in whatever medium is in question.  So a plane going Mach 1 is going at the speed of sound.  (In air, of course...if it were going Mach 1 through steel it would have to be going much faster, and it woudln't be going very far)  Mach 2 is twice the speed of sound.

Answer 2

It's Mach...not Mawk. And, Mach is equal to Velocity Relative to Medium divided by the Velocity of Sound Relative to the Medium.

That's the formula that you use to determine the Mach speed. Mach isn't a set value, so you can't just say something like "200km per second" or something like that. It's dependant on the pressure of the atmosphere, along with many other variables.

Hope this helps!

Answer 3

mach 1 is the speed of sound. speed of sound varies with altitude. at sea level it's about 750 mph.  mach 2=double it etc.

Answer 4

Multiples of the speed of sound.

Answer 5

The Mach number is commonly used both with objects traveling at high speed in a fluid, and with high-speed fluid flows inside channels such as nozzles, diffusers or wind tunnels. As it is defined as a ratio of two speeds, it is a dimensionless number. At a temperature of 15 degrees Celsius and at sea level, the speed of sound is 340.3 m/s (1,225 km/h, 761.2 mph, or 661.7 kn) in the Earth's atmosphere. The speed represented by Mach 1 is not a constant; For example, it is dependent on temperature and atmospheric composition. In the stratosphere it remains constant irrespective of altitude even though the air pressure varies with altitude.

Since the speed of sound increases as the temperature increases, the actual speed of an object traveling at Mach 1 will depend on the fluid temperature around it. Mach number is useful because the fluid behaves in a similar way at the same Mach number. So, an aircraft traveling at Mach 1 at sea level (340.3 m/s, 761.2 mi/h, 1,225 km/h) will experience shock waves in much the same manner as when it is traveling at Mach 1 at 11,000 m (36,000 ft), even though it is traveling at 295 m/s (654.6 mph, 1,062 km/h, 86% of its speed at sea level).

Answer 6

It's mach and it multiples of the speed of sound.  Mach 1= 750mph, Mach 2 = 1500  mph and so forth.

Answer 7

Mach.  Rhymes with "block."

Each Mach number is equal to a multiple of the speed of sound, but is usually about 750 MPH or 1140 feet per second.

Answer 8

It is Mach, not Mawk. Mach is the ratio of velocity of an object to the speed of sound in a medium. Speed of sound is dependent on temperature, thus Mach # is dependent on temperature (not altitude, even though it might look like so, because the higher you go, the colder it becomes)

You use this equation to calculate Mach #: Mach = Velocity (V)  divided by Speed of sound (a).

Speed of sound in a medium is equal to the square root of (gamma for air (which is 1.4) by gas constant for air (R which is 2870.5J/(Kg.K) by the Temperature). That is a=sqrt(Gamma*R*T).

So imagine a plane is travelling at 400MPH at a known altitude where the temperature is 32F (273K), the speed of sound is 331m/s (740MPH or 1191.6kmph).

Now the Mach at which the plane is travelling is 400MPH/740MPH = 0.54. Therefore the plane is travelling at MACH 0.54

I hope you understand this long logic. You can email me if you have any more questions. Good luck
