Suppose you have a cylindrical glass tube with a thin capillary opening, and you wish to determine the diameter
of the capillary. You can do this experimentally by weighing a piece of the tubing before and after filling a
portion of the capillary with mercury. Using the following information, calculate the diameter of the capillary.
Mass of tube before adding mercury = 3.263 g
Mass of tube after adding mercury = 3.416 g
Length of capillary filled with mercury = 16.75 mm
Density of mercury = 13.546 g/cm3
Volume of cylindrical capillary filled with mercury =
(p)(radius)2(length)
