A hydrometer is a buoyant device used for measuring the specific weight of a liquid. A weighed glass bulb floats below the surface with a graduated stem extending above the surface. The position of the fluid level on the steam corresponds to the specific gravity of the fluid. Given a hydrometer with a cylindrical bulb that has a diameter of 2 cm and a length of 8cm. The cylindrical stem has a diameter of 1 cm and a length of 8 cm. The mass of this instrument is 35 g. What is the range of specific gravities that can be measured with this hydrometer?
