TABLE 2.
Tabulation of the experimentally determined values of the speed of sound, the attenuation, and the nonlinear parameter B/A for all isopropanol concentrations. Also shown is the standard deviation associated with B/A as well as the percent error of B/A. The average uncertainty associated with measuring B/A was found to be 4.4%.
