Question
Blaise Pascal duplicated Torricelli's barometer using a red Bordeaux wine, of density 984 kg/m3, as the working liquid (figure below).
A long tube is upside-down, with its closed end in the air and its open end submerged in a tank of wine. A column of wine inside the tube extends from the surface level of the wine outside the tube to nearly the top of the tube. The height of the column is labeled h. The pressure outside the tube is labeled P0, and an arrow below the P0 label points down toward the surface of the tank.
(a) What was the height h of the wine column for normal atmospheric pressure?
m
(b) Would you expect the vacuum above the column to be as good as for mercury?
m
(b) Would you expect the vacuum above the column to be as good as for mercury?
