Bulk sound velocity

WebMar 5, 2014 · The speed of sound in solids is given by: v = K + 4 3 G ρ where K and G are the bulk modulus and shear modulus respectively. The bulk modulus of iron is 1.7 × 10 11 P a, the shear modulus is 8.2 × 10 10 P a and the density is 7874 k g / m 3, so the equation gives v = 5956 m / s. Webc = velocity of sound (m / s) B = bulk modulus of the medium (Pa) ρ = density of the medium (kg / m 3) which for air = 1.21 kg / m 3 The bulk modulus can be measured or can be calculated from an equation of state that relates the behavior of the pressure, density, and temperature in a gas.
