Web1 Answer Sorted by: 0 Flows in which the maximum Mach number is less than 0.3 are usually assumed to be incompressible. Consider gas at rest with density ρ 0 that is then accelerated isentropically to Mach number M. The density of the gas will change in this new state and is given by: ρ 0 ρ = ( 1 + γ − 1 2 M 2) 1 / ( γ − 1) WebThe speed at which sound propagates through a medium is related to the compressibility of that medium: the more compressible, the slower the speed of sound. The degree to which we have to consider compressibility when studying fluid flow is also linked to the speed of sound: as our flow speeds get closer to the speed of sound, compressibility ...
