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.
