Ultrasonic Characterization of Aqueous Polyvinyl Pyrrolidone (PVP)

Aim: Various thermo acoustic parameters such as adiabatic compressibility ( relaxation time( τ), acoustic impedance (z), classical absorption isothermal compressibility ( (C 1) of PVP solution were obtained from the measurement of ultrasonic velocity (u) , density( ρ) and viscosity( η). Methodology: All these measurements were made by Pulse Echo technique at different concentration of the range 0.05 to 0.3wt. Original Research Article
