5. Dez. 2015 · Speed of Sound. The speed of sound is the distance traveled over time by a sound wave in an elastic medium. The SI unit of speed is meters per second or (m/s). The speed of sound in dry air at 20 ° C is 343.2 m/s. In different mediums (gas, solids, or liquids) the speed of sound is different than 343.2 m/s.
Speed of Sound in Various Media. Table 17.1 shows that the speed of sound varies greatly in different media. The speed of sound in a medium depends on how quickly vibrational energy can be transferred through the medium. For this reason, the derivation of the speed of sound in a medium depends on the medium and on the state of the medium.
Figure 16.3.1: A sound wave moves through a volume of fluid. The density, temperature, and velocity of the fluid change from one side to the other. The continuity equation states that the mass flow rate entering the volume is equal to the mass flow rate leaving the volume, so. ρAv = (ρ + dρ)A(v + dv).
31. Mai 2013 · On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h). Because gas molecules move more slowly at ...
Let's be honest. All we really care about is the speed of sound in air. The speed of sound in air is approximately 345 m/s (about 1250 kph, 770 mph, 1100 ft/s). The speed of sound in air is nearly the same for all frequencies and amplitudes. It increases with temperature. The speed of sound in air as a function of temperature can be found using ...
