Ultrasonic absorption in water in the region of i mc. /s

ABSTRACT THE absorption of ultrasonic waves in liquids has been the subject of many investigations. In particular, many measurements have been made of the absorption in water as a function

of the temperature and frequency. For frequencies of 5 mc./s. and more, the latest published results for water agree well and seem to be accurate1. If _a_ is the absorption coefficient and

_f_ the frequency, _a/f_2 is found to be independent of the frequency and is 21 × 10-15 m.-1/sec.2 at 25° C. For frequencies near 1 mc./s. the absorption coefficient is approximately 0-2

db./m. This is too small to be measured accurately by the known methods. Access through your institution Buy or subscribe This is a preview of subscription content, access via your
