Derive speed of sound
WebCalculate the velocity of sound at this height using the following equation: v = 4f (H + 0.4D) Results The speed of sound in air is 343 m/s (nearly a mile in 5 seconds!) at 20°C. Compare your experimental value to the true … WebOct 28, 2024 · The speed of sound in fresh water 1,428 m/s. Water’s elastic bulk modulus is 2.2 × 10 9 Pa. Knowing these two values, we can confirm water’s density. Squaring both sides leaves: or Determining the Speed of Sound The density of cold-rolled steel is 7861 kg/m 3. Its elastic bulk modulus is 159 GPa.

WebMar 29, 2024 · In your derivation, you kept the temperature constant, so your result corresponds to isothermal sound waves, i.e. sound waves that are slow enough so that … WebSo, taking the second derivative with respect to time, its acceleration to the right is. Equation (1) gives the mass and the two equations above give F and a, so F = ma becomes ... Taking γ = 1.4 gives a speed of sound of …
WebFor helium, γ = 5/3 and the molecular mass is .004 kg/mol, so its speed of sound at the same temperature is. v sound in helium = m/s = ft/s = mi/hr. Doing this calculation for air at 0°C gives v sound = 331.39 m/s and at 1°C gives v sound = 332.00 m/s. This leads to a commonly used approximate formula for the sound speed in air:
