Mach number

Definition of Mach

Mach, commonly denoted M or Ma, is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Austrian physicist and philosopher Ernst Mach, who studied gas dynamics and shock waves. Mach number is used to classify the flow regimes based on the effects of compressibility and shock waves on the flow.

How to Convert Mach

To convert mach to other units of speed, we need to multiply by the local speed of sound in the medium, which depends on the temperature and pressure of the gas. For example, to convert mach to meters per second, we need to multiply by the speed of sound in air at sea level, which is about 340 m/s. To convert mach to kilometers per hour, we need to multiply by the speed of sound in air at sea level and by 3.6, since there are 3.6 seconds in one hour.

Here are some examples of how to convert mach to other units of length in the US Standard system and the SI system:

  • To convert 1 M to meters per second (m/s), we multiply by 340: 1 M x 340 = 340 m/s
  • To convert 2 M to kilometers per hour (km/h), we multiply by 340 and by 3.6: 2 M x 340 x 3.6 = 2448 km/h
  • To convert 3 M to miles per hour (mph), we multiply by 340 and by 2.2369362920544, since there are 2.2369362920544 miles in one kilometer: 3 M x 340 x 2.2369362920544 = 2285.714285714 mph
  • To convert 4 M to feet per second (fps), we multiply by 340 and by 3.2808398950131, since there are 3.2808398950131 feet in one meter: 4 M x 340 x 3.2808398950131 = 4465.306122449 fps
  • To convert 5 M to knots (kn), we multiply by 340 and by 1.9438444924406, since there are 1.9438444924406 nautical miles in one kilometer: 5 M x 340 x 1.9438444924406 = 3316.326530612 kn
  • To convert 6 M to centimeters per second (cm/s), we multiply by 340 and by 100, since there are 100 centimeters in one meter: 6 M x 340 x 100 = 204000 cm/s

Where Mach Is Used

Mach is used in various fields of science and technology where the speed and direction of movement of objects or phenomena are measured or applied in relation to the speed of sound in the medium. For example:

  • In aerodynamics and aeronautics, mach is used to measure the speed and performance of aircraft, rockets, missiles, and other flying vehicles, as well as the effects of air resistance, drag, lift, and thrust on them.
  • In acoustics and sound engineering, mach is used to measure the intensity and frequency of sound waves, as well as the effects of reflection, refraction, diffraction, interference, and Doppler shift on them.
  • In meteorology and climatology, mach is used to measure the speed and direction of wind, storms, hurricanes, tornadoes, and other weather phenomena, as well as the effects of temperature, pressure, humidity, and density on them.

History of Mach

The concept of mach number was first introduced by Swiss engineer Jakob Ackeret in his doctoral thesis in 1929. He proposed it as a convenient way to express the ratio of flow velocity to speed of sound in gas dynamics problems. He also named it after Ernst Mach, who had conducted experiments on supersonic projectiles and shock waves in the late nineteenth century.

The term mach number was later popularized by German-American engineer Theodore von Karman, who used it extensively in his research on aerodynamics and supersonic flight in the early twentieth century. He also established the first supersonic wind tunnel at Caltech in 1939.

The first human-made object to break the sound barrier was a rocket-powered plane called Bell X-1 piloted by Chuck Yeager in October 1947. He achieved a speed of about Mach 1.06 at an altitude of 13,000 meters.
The first human to travel faster than sound was Soviet cosmonaut Yuri Gagarin, who orbited the Earth at a speed of about Mach 25 in April 1961.
The fastest manned aircraft ever flown was the North American X-15, which reached a speed of about Mach 6.7 in October 1967.

The fastest unmanned aircraft ever flown was the NASA X-43A, which reached a speed of about Mach 9.6 in November 2004.

  • To convert 6 M to centimeters per second, we multiply by 340 and by 100: 6 M x 340 x 100 = 204000 cm/s
  • To convert 7 M to millimeters per minute, we multiply by 340 and by 1000, since there are 1000 millimeters in one meter, and multiply by 60, since there are 60 minutes in one hour: 7 M x 340 x 1000 x 60 = 142800000 mm/min
Mach speed can be marked as Ma and Mach number. At Standard Sea Level conditions (temperature of 15 degrees Celsius), the speed of sound = 1 Mach = 340.3 m/s (1225 km/h, or 761.2 mph, or 661.5 knots, or 1116 ft/s).

Miles Per Day

Definition of Miles Per Day

Miles per day (mi/d) is a unit of speed that measures how fast something is moving in terms of miles per unit of time. It is commonly used in the United States, the United Kingdom, and some other countries that use the US Standard system of measurement or have close historical ties with them. It is often used for measuring the average speed or distance traveled by an object or phenomenon over a period of time that is measured in days or longer.

One mile per day is equal to 0.0416666667 miles per hour, or 0.0185185185 meters per second. It can also be converted to other units of speed, such as kilometers per hour, feet per second, or knots, by using appropriate conversion factors.

How to Convert Miles Per Day

To convert miles per day to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert miles per day to kilometers per hour, we need to multiply by 1.609344, since there are 1.609344 kilometers in one mile. To convert miles per day to meters per second, we need to multiply by 0.018518518518519, since there are 0.018518518518519 meters in one mile.

Here are some examples of how to convert miles per day to other units of length in the US Standard system and the SI system:

  • To convert 10 mi/d to kilometers per hour (km/h), we multiply by 1.609344: 10 mi/d x 1.609344 = 16.09344 km/h
  • To convert 20 mi/d to feet per second (fps), we multiply by 0.05787037037037, since there are 0.05787037037037 feet in one meter: 20 mi/d x 0.05787037037037 = 1.157407407407 fps
  • To convert 30 mi/d to knots (kn), we multiply by 0.03626111111, since there are 0.0362611111 nautical miles in one mile: 30 mi/d x 0.0362611111 = 1.08783333 kn
  • To convert 40 mi/d to meters per second (m/s), we multiply by 0.018518518518519: 40 mi/d x 0.018518518518519 = 0.740740740741 m/s
  • To convert 50 mi/d to meters per minute (m/min), we multiply by 1.11111, since there are 1.11111 minutes in one hour: 50 mi/d x 1.11111 = 55.555555556 m/min
  • To convert 60 mi/d to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and multiply by 0.018518518518519: 60 mi/d x 100 x 0.018518518518519 = 111.11111 cm/s

Where Miles Per Day Are Used

Miles per day are mainly used for measuring the average speed or distance traveled by an object or phenomenon over a period of time that is measured in days or longer. They are often used in fields such as travel, fitness, sports, and geography, where the speed or distance traveled by an object or phenomenon is measured in terms of miles per unit of time.

For example, a person may travel an average of 100 mi/d on a road trip across a country, which means that they cover an average distance of 100 miles in one day. A runner may run an average of 5 mi/d as part of their training routine, which means that they run a distance of 5 miles in one day. A planet may have an orbital velocity of thousands of miles per day, which means that it covers thousands of miles along its orbit in one day.

Miles per day are also used in some other fields where the speed or distance traveled by an object or phenomenon is measured in terms of miles per unit of time.

History of Miles Per Day

The origin of miles per day as a unit of speed can be traced back to the development of the US Standard system and the mile as a unit of length in the late eighteenth century. The mile was defined as one thousand six hundred and nine meters (or eight furlongs) based on the English statute mile.

The term mile first appeared in English in the late fourteenth century, but it was not until later in the early nineteenth century that the use of miles per day became more common; before that, other units such as miles per hour or leagues per day were preferred for expressing speed.

Miles per day have been used ever since as a standard unit of speed for measuring the average speed or distance traveled by an object or phenomenon over a period of time that is measured in days or longer. They have also been adopted by some international organizations and conventions, such as the International System of Units and the International Astronomical Union.
