Determination of the Velocity of Sound in Distilled Water

Abstract

The velocity of sound is determined in distilled water over the temperature range from 22 to 25°C. The method used consists of measuring the transit time of two sound paths of different lengths traveling between the crystal faces of two barium-titanate transducers. With an accurate measure of the length, the velocity is determined from the quotient of ΔI/Δt. It is believed that the accuracy of the measurements is within ±1 ft/sec.
