Mach (20°C, 1 atm)
Ma
Definition
Mach at 20°C and 1 atmosphere is the speed of sound in air under these specific conditions, approximately 343.6 meters per second. It is used as a reference for measuring high speeds, particularly in aviation and aerospace applications.
History/Origin
The Mach number was named after Austrian physicist Ernst Mach and became the standard for measuring high speeds in aviation. It represents the ratio of an object's speed to the speed of sound in the surrounding medium.
Current Use
Mach is used in aviation for measuring aircraft speeds, in aerospace engineering for high-speed vehicle design, and in various applications involving high-speed motion. It is particularly important for supersonic and hypersonic flight.
