Speed of sound in water by a direct method

The speed of sound in distilled water wa,s m eas ured over the temperature ra nge 0° to 100° C with an acc uracy of 1 part in 30,000. The results are given as a fifth-d egree polynomial and in tables . The water was contained in a cylindrical tank of fixed lengt h, terminated at each end by a plane transducer, and the end-to-end time of flight of a pulse of sound was determined from a measurement of t he pulse-repetition frequency required to set the success ive echoes into t im e coincidence.
