Surface tension measurement by Du Noüy ring method

WebThe surface tension of urine has been simply and rapidly measured using two methods, the DuNouy ring detachment method and the Wilhelmy blade immersion method. The methods agree, the correlation coefficient, r, was 0.992. The effect of ageing of the surface, of storage, of temperature, pH, dilution and albumin on urine surface tension are ... WebTo measure the surface tension between a liquid and the air, the duNouy ring is placed below the surface of the liquid. This test is performed by pulling the ring upward through the surface of the liquid. The force needed for the ring to break the surface (overcome the surface tension) is determined. This measurement is in dynes/centimeter. cingular at\u0026t flip phone 2
