SUMMARY

The discussion centers on the A.P. French equation related to singing wine glasses, specifically the constant β (beta). The value of β can be calculated using the formula: β = 0.3 - 1.229 x 10^-4 x abs(965 - density of liquid). This calculation is crucial for understanding the acoustics of singing wine glasses. A reference document detailing this equation is provided for further reading.

PREREQUISITES
  • Understanding of the A.P. French equation
  • Basic knowledge of acoustics
  • Familiarity with liquid density measurements
  • Access to the document on singing wine glasses
NEXT STEPS
  • Research the A.P. French equation in detail
  • Study the principles of acoustics related to liquid dynamics
  • Explore the effects of liquid density on sound frequency
  • Read the linked document on singing wine glasses for practical applications
USEFUL FOR

Physics enthusiasts, acoustics researchers, and anyone interested in the science behind singing wine glasses will benefit from this discussion.

Hi everyone

I have been working with singing wine glasses and the A.P French equation - I was just wondering if there is a value or way to work out the value of the constant in the equation?

I have a basic understanding of physics but yeah haha...

Cheers guys

AP French Constant

The AP French equation is very complex and I am assuming the constant that you are referring to is β (beta).

If so, the value of β can be calculated using the equation:
β=0.3-1.229x10^-4 x abs(965-density of liquid)

This equation is discussed in the document I have linked below:

Hope this helps
