Velocity of sound in copper-nickel blend

In summary, the conversation discusses finding the longitudinal velocity of sound in a 65/35 copper nickel blend and the possibility of using the equation sqrt(youngs modulus/density) to make an estimation. It is also mentioned that other users may have access to charts or tables with this information and that interpolating E values from other alloys could also help with the 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.
 

1. What is the velocity of sound in a copper-nickel blend?

The velocity of sound in a copper-nickel blend can vary depending on the specific composition of the blend, but on average it is around 4700 meters per second.

2. How does the velocity of sound in copper-nickel compare to other materials?

The velocity of sound in copper-nickel is relatively high compared to other materials. For example, the velocity of sound in water is around 1500 meters per second, while in air it is around 340 meters per second.

3. What factors can affect the velocity of sound in a copper-nickel blend?

The composition, temperature, and density of the blend can all affect the velocity of sound. Other factors such as impurities and crystal structure can also play a role.

4. How is the velocity of sound in a copper-nickel blend measured?

The velocity of sound in a copper-nickel blend can be measured using various methods such as ultrasonic testing, resonant ultrasound spectroscopy, and laser ultrasonics.

5. What are the practical applications of knowing the velocity of sound in a copper-nickel blend?

The velocity of sound in a copper-nickel blend is important in industries such as marine engineering, where this blend is commonly used for ship hulls and propellers. It is also used in various other applications such as heat exchangers, electrical components, and musical instruments.
