Abstract
The discharge coefficient of small holes drilled through a rotating cylinder wall were studied experimentally, as a fundamental study of the centrifugal gas-liquid or liquid-liquid centactor.The results are as follows:(1) It is confirmed experimentally that the discharge pressure of liquid under the contrifugal force is represented by Eq.(1), and the discharge coefficient, by Eq. (2).(2) The discharge coefficient depends upon the diameter of hole, the thickness of the wall and Red, but as far as the discharge coefficient defined by Eq. (2) is concerned, no difference is recognized whether it is in the centrifugal field or in the gravitational field.(3) The effect of liquid viscosity on the discharge coefficient is covered by Red.(4) All the experimental results obtained of the effect of liquid surface tension agree with the results of the theoretical consideration introduced in the previous paper, as shown in Fig. 15. Taking into account the surface tension, the discharge coefficient is presented by Eq. (5): and the effect of surface tension is considered negligible when the Weber number is greater than 1, 000.
