Calculating Relative Sound Velocities of Sea Salts by A New Method
Afshin Mohseni Arasteh, Kamran Lary, Sara Allahyari Beik
Relative sound velocity (U-U0) of several solutions were measured from 0.01 to 1.0 at 25 °C. The sound velocities were fitted to a function of molality (maximum standard deviation 0.05 m/s) U = U0 + Am + Bm3/2 + Cm2 , where U0 is the sound velocity in pure water, U = sound speed in given solution, m = molality and A, B and C = temperature dependent parameters. The sound speed of sea water calculated with the direct measurement.
