Question

Glycerin is poured into an open U-shaped tube until the height in both sides is 22cm . Ethyl alcohol is then poured into one arm until the height of the alcohol column is 22cm . The two liquids do not mix. Part A What is the difference in height between the top surface of the glycerin and the top surface of the alcohol? Express your answer with the appropriate units.

Explanation / Answer

Density of:
alcohol, ethyl (grain) - 789.2
glycerin - 1260

The pressure at the border between the alcohol and the glycerol is p(a) = ?gh
p(a) = 789,2*g*0.22
at the same height on the other side is the pressure equally large. And this pressure is
p(g) = 1260*g*s ( s = height of glycerin above the alcohol/glycerin border level)
p(g) = p(a)
1260s = 789,2*0.22
s = 0.1378 m = 13.78 cm
The difference between h and s = 8.22 cm,
