When a hydrometer (see Fig. P2.145) having a stem diameter of \(0.30 \mathrm{in}\). is placed in water, the stem protrudes \(3.15 \mathrm{in}\). 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 \(0.042 \mathrm{lb}\).
