Abstract
The direct impact of two cylindrical jets of liquid causes the liquid to emerge radially in a plane at right angles to the common axis of the jets. The maximum diameter of the disc of moving liquid so formed is shown to depend on the surface tension of the liquid. A method of measuring surface tension is developed and is applied to measure the surface tension of water, giving 73.83+-0.13 dyne/cm. at 15degC. The liquid surface is renewed about 80 times per second, contamination being thus prevented. The only other method in which such rapid renewal of the surface takes place is the Rayleigh oscillating-jet method. The angle of contact is not involved in Rayleigh's method, nor in the present method.
