? Suck out a little air throughthe rubber tube, noting the be-havior of the liquids. What pres-sure causes the liquids to rise in thetubes ? Again remove air by suctionuntil the water column is pushedup nearly to the top of its tube.Pinch the rubber tube tightly andclose the screw compressor.… … Fig. 21. SPECIFIC GRAVITY OF A LIQUID 57 up into the tubes? How does this pressure compare with thedownward pressure of each liquid? Compare, then, thedownward pressure of the water column with that of the saltsolution. Measure with a meter stick the length of the watercolumn above the level of the…
