A hydrometer is a device which uses the principle of buoyancy to measure the specific gravity of a liquid. Design a pocket-sized hydrometer that can be used to measure S.G. for liquids having 1.2< S.G. < 1.5. Specify important dimensions and the mass of the device. Write a brief report to your instructor explaining how you arrived at the final design. Also include a sketch showing the calibrated scale from which one would read S.G. In addition, construct a model and attach the scale to the worki
