2.145 When a hydrometer (see Fig. P2.145 and Video V2.8)having a stem diameter of 0.30 in. is placed in water, the stem protrudes 3.15 in. above the water surface. If the water is replaced with a liquid having a specific gravity of 1.10. how much of the stem would protrude above the liquid surface? The hydrometer weighs 0.042 lb.
