When Chuck Yeager broke the sound barrier with the Bell X-1 rocket plane in 1947, his mum wasn’t mad. This was one case where breaking something was a good thing.
14.1 Speed of Sound, Frequency, and Wavelength
WebThus, it is reasonable that the speed of sound in air and other gases should depend on the square root of temperature. 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 17.6 shows how a bat uses the speed of sound to sense distances. WebJan 16, 2024 · The speed of sound (Mach 1) varies with altitude and temperature. If an aircraft is travelling at the speed of sound at sea-level then its speed will be 661 knots … dairy farmers of britain
Speed of Sound in Air - The Physics Factbook - hypertext-book
WebThe speed of sound in air (or in other gases) can be expressed as c = (k p / ρ)1/2 = (k R T)1/2 (1) where c = speed of sound (m/s, ft/s) k = ratio of specific heats (adiabatic index, isentropic expansion factor) p = pressure (Pa, psi) R = 286.9 (J/kg K) = 1,716 (ft lb/slug oR) = individual gas constant specific for air WebWhile this is indeed the case up to about 36,000 ft (11,000 m), the speed of sound eventually reaches a constant, then starts rising again, reaches a new constant, starts decreasing again, reaches a new constant, then starts rising yet again!
