Definition of mach speed
WebDec 20, 2024 · Mach number is the coefficient phrase used to describe motion in the air. In fluid dynamics, the Mach number expresses the ratio of flow velocity past a boundary to local sound speed. The Mach number is crucial in the study of approximations that can be used to treat a flow as an incompressible flow. Mach number can also be used to … WebMach will go up, as you increase in altitude. This is because the lower density air lowers the speed of sound (in an absolute sense). True airspeed will go up as you maintain a constant indicated airspeed. Conversely, maintaining a constant true airspeed will increase your indicated airspeed as you descend.
