A 90mm high metal frame having trough of 115x40x10mm. Frame having 6 holes fitted with corks. Trough with capillary tubes of different bore; 150mm in length..
For demonstrating the relationship between capillary pressure and the bore diameter of the capillary tube. The apparatus comprises of a metal frame arrangement whose base is like a trough and the upper part of the frame supports six capillary tubes of different box. The trough is filled with water and the difference in heights of the resulting columns of water in the tubes is readily apparent. Overall height of frame 90 mm length of capillary tubes 150 mm
