Yg. Li et al., Improved computation of pressure coefficient and temperature coefficient of ultrasonic velocity in organic liquids, CHIN SCI B, 44(19), 1999, pp. 1770-1773
Based on Jacobson's molecular free length theory in liquids and the relatio
nship between the ultrasonic velocity and the molecular free length in orga
nic liquids, the equations of pressure coefficient and temperature coeffici
ent of ultrasonic velocity in organic liquids are derived. The calculated p
ressure coefficient and temperature coefficient of ultrasonic velocity are
in good agreement with the measured results.
