VENTURI TUBE DEMONSTRATOR (0034)
Similar devices fine extensive application in everything from carburetors of IC engines to aircraft airspeed indicators. Comprising of a horizontal glass tube having three cross sections along its length ? wide, narrow and wide respectively, with wide cross-sections having same size. One short, side tuba projects from each of the three cross-sections for connecting to the manometric tubes. Also included is a three-legged manometric tube joined to a common horizontal tube. When gas is flowing through the venturi tube with manometer filled with colored water, the relative pressure at the three points of the tube is evident from the water level in manometers

HARE'S APPARATUS - MOUNTED (0037)
Comprising a three limbed glass tube mounted on a wooden stand with a scale graduated 0-50cm x 1 mm. Rubber tubing attached to the third short central limb is used to apply suction to the two longer tubes. The height of liquids ih both the longer columns relates to their respective densities, the comparison of which directly implies the ratio of their densities. To facilitate The column height readings both the longer tubes are equipped with a vertical sliding index pointer

CAPILLARY TUBE APPARATUS (0040)
The appratus shows the relationship between capillary pressure or level of liquid in capillary and the bore diameter of the capillary tube. The apparatus comprises a rectangular sheet-metal frame, the base of which takes the form of a trough for holding water. The upper part of the frame supports six capillary tubes, each of a different bore, in the holed rubber bung with their lower ends resting in the trough underneath. The difference in heights of the resulting columns of water in each capillary tube is readily apparent. Length of capillary tubes about 150mm
