D = 1.25 × 10^−2 m and rise of water in capillary ,
h = 1.45 × 10^−2 m. Taking g = 9.80 m/s^2 and using the relation T = (rgh/2) × 10^3 N/m ,
The following observations were taken for dtermining the surface tension of water by capillary tube method: diameter of capillary ,
what is the possible error in measurement of surface tension T? ,
A uniform capillary tube of inner radius r is dipped vertically into a beaker filled with water. The water rises to a height h in the capillary tube above the water surface in the beaker. The surface tension of water is σ. The angle of contact between water and the wall of the capillary tube is θ. Ignore the mass of water in the meniscus. Which of the following statements is (are) true?
