Glycerin is poured into an open U-shaped tube until the height in both sides is 34 cm. Ethyl alcohol is then poured into one arm until the height of the alcohol column is 20 cm. The two liquids do not mix. What is the difference in height between the top surface of the glycerin and the top surface of the alcohol? I keep getting 12.6 cm as the answer but it is wrong. please help!!

Answer #1

Your process till height = 12.6 cm is correct.

Now read the question one more time.

We need the difference in height between to top surface of glycerin and top surface of the alcohol

given that height of ethyl alcohol = 20 cm

we got h = 12.6 cm = that is height of glycerin in other arm

Now difference between both heights will be = 20 - 12.6 = 7.4 cm

Please Let me know if you need anything else.

Please Upvote.

At same hight

Pressure in glycerin side = pressure in alcohol side

Pg = Pa

rho_g*g*hg = pho_a*g*ha

ha = 20 cm

hg = 20*790/1260 = 12.54 cm

A long, clear, flexible tube is bent into a U shape(open at both ends), and we pour water into it (density 1000 kg/m3)until the water reaches the same level on both vertical sides. Now we pour a 7 cm column of mercury into the left side(density 13,600 kg/m3), which does not mix with the water. (a)When the fluids reach equilibrium, find the difference in elevation between the top of the mercury (on the left) and the top of the water...
