Convert mach (20 Celcius dry air) to sound speed in air (20 Celcius 60 per cent humidity)
Selected category: speed.
Definition and details for mach (20 Celcius dry air):
Mach (M or Ma) is a relative speed unit, used to compare an aircraft's speed with the speed of the sound in the atmosphere. It was named "Mach" to honor the Austrian physicist Ernst Mach (1838-1916). But because sound speed value depends on the density and temperature of the air, sometimes mach is calculated at 20 ºC in dry air. Conversion center, here uses these initial conditions.
Definition and details for sound speed in air (20 Celcius 60 per cent humidity):
Sound speed in the air varies depending on the density and temperature of the air. Conversion center here calculates sound speed at 20 ºC and 60% humidity air
