Temperature dependent acoustical properties of mannitol+water using ultrasonic flow detector

Effect of concentration as well as temperature dependent acoustical properties of mannitol in water has been investigated at different temperature. Ultrasonic pulse echo technique at 5 MHz frequency has been employed for this purpose. Acoustic parameters such as ultrasonic velocity (ν), Compressibility (β), Free length (Lf), Acoustic Impedance (Z), Rao’s constant (R) and Wada’s constant (W) has been calculated and discussed in terms of structural dynamics, inter and intramolecular H-bonding & intermolecular forces between solute and solvent molecules.
