Course Outcomes:
Upon successful completion of this course, students should be able to:
CO1: Learn about the nature and applications of Acoustical waves.
CO2: Apply the concept in many diversified areas which include fluid mechanics, communication, NDT (Non Destructive
Testing), SONAR, Real time tracking of objects and devices, imaging (i.e. sonography), medicine, cleaning, welding etc.
CO3: Identify the ultrasonic parameters and deviation in viscosity and infer the results in determining the interaction types, in
the Binary and Ternary mixtures.
CO4: Apply the measured viscosity and ultrasonic velocity data to various theories in determining the best applicability of the
theory for the given binary mixture.
CO5: Apply Acoustic ultrasonic in appropriate applications.
