Speed of sound at altitudes
WebAt Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number.

WebSep 12, 2024 · While not negligible, this is not a strong dependence. At 0°C , the speed of sound is 331 m/s, whereas at 20.0 °C, it is 343 m/s, less than a 4% increase. Figure 17.3. 3 shows how a bat uses the speed of sound to sense distances. Figure 17.3. 1: A bat uses sound echoes to find its way about and to catch prey. WebAt the temperature of ϑ = 0°C the speed of sound in dry air was determined to be c = 331.3 m/s. 0°C equals 68°F. It makes no sense to give the speed of sound adding the words at the "standard atmosphere at sea level". To get the speed of sound the temperature is important, not the barometric pressure.

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on … See more Sir Isaac Newton's 1687 Principia includes a computation of the speed of sound in air as 979 feet per second (298 m/s). This is too low by about 15%. The discrepancy is due primarily to neglecting the (then unknown) effect of … See more The transmission of sound can be illustrated by using a model consisting of an array of spherical objects interconnected by springs. In real material terms, the spheres represent the material's molecules and the springs represent the See more In the Earth's atmosphere, the chief factor affecting the speed of sound is the temperature. For a given ideal gas with constant heat capacity and composition, the speed of sound is dependent solely upon temperature; see § Details below. In such an ideal case, … See more General physical considerations The medium in which a sound wave is travelling does not always respond adiabatically, and as … See more The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "velocity". See more The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In solids, the speed of transverse (or shear) waves depends on the shear deformation under shear stress (called the See more Speed of sound in ideal gases and air For an ideal gas, K (the bulk modulus in equations above, equivalent to C, the coefficient of … See more WebApr 29, 2024 · The most accurate speed of sound measurements were actually recorded between the ground at 2,000 m or 2km (~ 6,000 feet altitude) and about 6,000 m (18,000 …
