What does Mach (SI standard) represent?

Mach (SI standard) is a dimensionless number representing the ratio of an object's speed to the local speed of sound in the surrounding medium, used to classify speeds such as subsonic or supersonic.

Why convert Mach to velocity of sound in pure water?

Converting Mach to velocity of sound in pure water helps relate aerospace speed references to underwater acoustic speeds, useful in sonar interpretation and underwater equipment design.

Are conversions from Mach to underwater sound velocity exact?

No, conversions assume standard reference conditions and do not account for environmental variations, so results require contextual interpretation.

Examples

1 Mach (SI standard) equals 0.1989926485 times the velocity of sound in pure water.
5 Mach (SI standard) equals 5 multiplied by 0.1989926485, resulting in approximately 0.9949632425 in velocity of sound in pure water.

Common Use Cases

Describing aircraft or spacecraft speeds relative to underwater acoustic speeds.
Analyzing sonar and echo-sounding data by relating acoustic travel times to speed values.
Supporting oceanographic profiling and underwater acoustic equipment design.
Calibrating and predicting performance of underwater sonar and hydrophone systems.

Tips & Best Practices

Always consider that Mach depends on local air temperature and composition while water sound speed depends on temperature and pressure.
Use standard reference conditions when applying this conversion for consistency.
Interpret results contextually due to differing units and environmental influences.
Verify environmental conditions if precise conversion accuracy is required.

Limitations

Mach number varies with air temperature and composition, while underwater sound velocity varies mainly with water temperature and pressure.
Mach is dimensionless and relative, whereas velocity of sound in pure water is an absolute measure in metres per second.
Environmental changes such as salinity or pressure affect the underwater sound speed, potentially limiting conversion accuracy.
The conversion assumes standard conditions and may not be precise without condition-specific corrections.
