Repeat Prob. 7115, but with the distance r from the sound source as an additional independent parameter.
Question:
Repeat Prob. 7–115, but with the distance r from the sound source as an additional independent parameter.
Data from Problem 115
Sound intensity I is defined as the acoustic power per unit area emanating from a sound source. We know that I is a function of sound pressure level P (dimensions of pressure) and fluid properties ρ (density) and speed of sound c.
Use the method of repeating variables in mass-based primary dimensions to generate a dimensionless relationship for I as a function of the other parameters. Show all your work. What happens if you choose three repeating variables? Discuss.
Repeat part (a), but use the force-based primary dimension system. Discuss.
