SUMMARY

The longitudinal velocity of sound in a 65/35 copper-nickel blend can be estimated using the equation sqrt(Young's modulus/density). This method is validated by the discussion participants, who confirm that the units are consistent. For a more accurate estimation, it is recommended to interpolate Young's modulus values from other copper-nickel alloys, particularly the 70/30 blend, which is more commonly referenced. This approach allows for a reasonable approximation of the velocity of sound in the specified alloy.

PREREQUISITES
  • Understanding of Young's modulus and its significance in material science
  • Knowledge of density and its role in calculating sound velocity
  • Familiarity with copper-nickel alloy compositions and properties
  • Basic mathematical skills for applying the equation sqrt(E/rho)
NEXT STEPS
  • Research the Young's modulus values for various copper-nickel alloys
  • Learn about the properties and applications of the 70/30 copper-nickel alloy
  • Explore methods for interpolating material properties from known data
  • Investigate other factors affecting sound velocity in metallic alloys
USEFUL FOR

Material scientists, metallurgists, and engineers involved in the study of alloy properties and sound transmission in materials.

I'm trying to find the longitudal velocity of sound in a 65/35 copper nickel blend. If anyone has a chart/table/resource of some sort that would be awesome.

If not I should be able to find this using the equation sqrt(youngs modulus/density) correct? If that's the case I can make some assumptions and a fairly close guess to the vos using the youngs modulus and density of the more popular 70/30 copper nickel alloy

Welcome to PF, Mx.
Fred Garvin and Astronuc seem to be able to pull charts like that out of their butts on a moment's notice, so help is probably on its way. :biggrin:
 
Your equation, sqrt(E/rho), sounds right. The units come out right at least. Perhaps you would consider interpolating E values from some other alloys?

You might be able to make a nice estimate with the values of E for Cu, Ni and 70/30.
