A hydrometer consists of a spherical bulb with a cylindrical stem (figure below). The cross-sectional area of the stem is 0.59 cm2. The total volume of bulb and stem is 13 cm. When immersed in water, the hydrometer floats with 8 cm of the stem above the water surface. In alcohol, 1 cm of the stem is above the surface. Find the density of alcohol. 8.0 cm 1.0 cm water

A hydrometer is an instrument used to determine liquid density. A simple one is sketched in the figure below. The bulb of a syringe is squeezed and released to let the atmosphere lift a sample of the liquid of interest into a tube containing a calibrated rod of known density. The rod, of length L and average density rho_0, floats partially immersed in the liquid of density rho. A length h of the rod protrudes above the surface of the...
