Publisher's Synopsis
Excerpt from An Interference Method for the Measurement of the Speed of Sound in Liquids
A long series of experiments on the speed of sound was 'con ducted by M. G. Wertheim (i) at Paris. His method was indirect He immersed organ pipes in water and sounded them by forcing a current of water through them. The note was determined by compar1son with a sonometer. Varying the pressure under which the water was forced through the pipes caused them to give different harmomcs; From these the pitch of the fundamental was calculated. Certain corrections depending on the shape and diameter of the pipe having been applied, the speed of sound in the liquid was Obtained by multiplying. The wave-length -by the vibration number. The mean of 58 experiments at temperatures between 15 and 20 degrees was meters per second.
