Mach Number

The Mach number is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound.

The Mach number equals the characteristic speed divided by the speed of sound.

Formula

QuantityVariable["Ma", "MachNumber"] == QuantityVariable["v", "Speed"]/QuantityVariable["c", "SoundSpeed"]

symbol description physical quantity
Ma Mach number "MachNumber"
c sound speed "SoundSpeed"
v characteristic speed "Speed"
