? 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 thedownivard 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…
