Speed Of Sound In Vulcanized Rubber

Wavelength λ.

Speed of sound in vulcanized rubber.

So it is reasonable that the speed of sound in air and other gases should depend on the square root of temperature. Pratima bajpai in biermann s handbook of pulp and paper third edition 2018. Liquids liquids temperature c density kg m 3 adiabatic bulk modulus pa ratio of specific heats speed of sound m sec water fresh 20 998 2 18 10 9 1 004 1481 water sea 13 1026 2 28 10 9 1 01 1500 mercury 20 13 600 25 3 10 9 1 13 1450 table 3. One of the earliest industrial developments was the use of natural soft rubber poly cis isoprene in the early 1800s.

What is sppeed of sound in volcanised rubber. Vulcanized rubber is even softer than rubber. List the given and unknown values. For vulcanized rubber the young s modulus y 2 8 10 n m and the density around 920 kg m.

If the speed of sound is known to be 350 m s what is the wavelength of this note. Ask for details. Solid speed of sound m sec granite 6000 vulcanized rubber at 0 c 54 table 2. The silicone rubber doped with yb2o3 powder showed a sound speed of 0 88 km s an acoustic impedance of 1 35 x 10 6 kg m2s an acoustic attenuation of 0 93 db mmmhz and a shore a hardness of 55.

At 0 oc the speed of sound is 331 m s whereas at 20 oc it is 343 m s less than a 4 increase. So the pressure changes in it due to sound waves are not much. While not negligible this is not a strong dependence. So speed of sound 55 1 m sec.

The development of the vulcanization process reaction of the carbon double bonds with sulfur to form cross linked chains by goodyear in 1839 led to hard rubber. Follow report by priyanshuraj90 17 11 2018 log in to add a comment. Write the equation for wave speed and rearrange it to solve for. Wave speed the musical note a above middle c has a frequency of 440 hz.

The density of a medium is the second factor that affects the speed of sound.
