sound travels at 1126 ft/sec in airto calc in other mediumswhereK is a coefficient of stiffness, the bulk modulus (or the modulus of bulk elasticity for gases), is the density
Young's modulus is SI system is GPa (Giga-pascal). A Pa is a pascal with base units of Newtons per meter squared, or kilogram-meter/second squared per meter squared
I meant lower linear density, but I can't change it. So for example for Aluminum the Linear density of [111] is lower than for [110] and that is again lower than [100]. But you notice that the modulus of elasticity is higher for [111] than for [110] and that again is higher than for [100]
equation for speed of sound in a medium: c=sqrt(B/rho) B=bulk modulus rho=density all else being constant, and increase in temperature will cause an expansion (usually) of the material. The expansion will decrease the density (mass per unit volume) and thus increase the speed of sound through the material.
The speed of sound through an object is related to the density and elasticity of the material. Velocity = square root of (elasticity (bulk modulus) divided by density). Thus if you can measure the material's elasticity and the velocity of sound waves passed through it, the density can be calculated without reference to the mass of the object.
The speed of sound varies with various factors such as temperature,nature of the material,physical state of the substance,etc.
As the Young's modulus is a measure of stiffness, an increase in the temperature will typically lead to a decrease in the modulus of elasticity. However it depends on the material.
It depends on the resin; most exhibit a Young's modulus between 100,000 and 1,000,000 psi at room temperature.

For a liquid, we find that the speed of sound decreaseswith increasing density but increases with increasing bulk modulus. Increasing the dissolved solids will increase density, but also bulk modulus. In general, bulk modulus will increase "faster" with an increase in dissolved solids than density will increase. And this translates into a net increase in the speed of sound in water with increasing dissolved solids. Tap water has dissolved solids, so the speed of sound in tap water should be higher than it is in pure water at the same temperature and pressure.
it is around 1 GPa or lower.. depending on the type/density

As a high performance material, pure tungsten has high melting temperature, high density, low vapor pressure, low thermal expansion combined with good thermal conductivity, sufficient electrical resistance and high modulus of elasticity.
Did you mean A36 steel? As with most steels, A36 has a density of 7,800 kg/m3 (0.28 lb/cu in). Young's modulus for A36 steel is 200 GPa (29,000,000 psi). A36 steel has a Poisson's ratio of 0.32, and a shear modulus of 78 GPa (11,300,000 psi)
c=sqrt(K/rou),here cf is the speed of sound, K is the bulk modulus, rou is the density. so if we know the density of ocean water and sound speed, we can get K = c^2*rou=1500^2*1024 = 2.304*10^9 (N/m^2)
