Helium speed of sound

Web3 mei 2024 · We all know that helium is lighter than air — that’s why helium-filled balloons float. Inside of an air-filled hard drive there are rapidly spinning disk platters that rotate at a given speed, 7200 rpm for example. The air inside adds an appreciable amount of drag on the platters that in turn requires an appreciable amount of additional ... WebIf we call room temperature 298 K, the speed of sound works out to 346 m/s. For helium, of course, both γ and M are different. γ = 1.67, and M = 4.003 × 10 -3 kg/mol. So for helium the equation above gives v = 973 m/s at STP, and 1,020 m/s at 298 K.

Speed of sound in hydrogen vs. speed of sound in air

WebThis naturally means sound travels faster in Helium than in air. Now, we know the other old equation: Speed = Wavelength x Frequency Now since we know that the FREQUENCY of sound is the same in Helium and in Air, and the speed of sound is greater in Helium, it follows that the Wavelength of sound is greater in Helium than in Air .

WebThe speed of sound varies greatly depending upon the medium it is traveling through. The speed of sound in a medium is determined by a combination of the medium’s rigidity (or compressibility in gases) and its density. The more rigid (or less compressible) the medium, the faster the speed of sound.
