Acoustical Properties of Aqueous Solutions of Urea: Reference Data for the Ultrasonic Spectrometry of Liquids
The density, sound velocity, and ultrasonic attenuation coefficient of aqueous solutions of urea were measured at temperatures between 10 °C and 35 °C and at concentrations ranging from 0 to 9 mol/L (≡21.7 mol %) urea. The data are correlated using simple empirical expressions, and the isentropic co...

| Zusammenfassung: | The density, sound velocity, and ultrasonic attenuation coefficient of aqueous solutions of urea were measured at temperatures between 10 °C and 35 °C and at concentrations ranging from 0 to 9 mol/L (≡21.7 mol %) urea. The data are correlated using simple empirical expressions, and the isentropic compressibilities are calculated. These urea solutions provide a favorable set of reference data for acoustical measurements of liquids with sound velocity between 1500 m·s-1 and 1700 m·s-1. |
