AI Thread Summary
The discussion focuses on calculating the longitudinal velocity of sound in a 65/35 copper-nickel blend. The equation suggested for this calculation is the square root of Young's modulus divided by density, which appears to be correct. Participants encourage using interpolation of Young's modulus values from similar alloys, particularly the 70/30 copper-nickel alloy, to make a more accurate estimate. Resources or charts for specific values are sought, with some members expected to provide assistance. Overall, the conversation emphasizes the importance of using known properties of related alloys for estimation.

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.
