30 in weighs 0.042 lbf in air. Consider the A hydrometer with a stem diameter following:...
When a hydrometer 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 1.19, how much of the stem would protrude above the liquid surface? The hydrometer weighs 0.042 lb .
