Short #40 - Specifically Relative

<p>In today's short podcast episode, we talk about specific gravity, also known as relative density. We explain why it matters to technicians.</p> <p>When we talk about specific gravity, we're actually talking about density. We're actually using that value to assess how a vapor or liquid's density compares to air or water, respectively. Regardless, we are working with the pressure conditions of 14.7 PSIA, or atmospheric pressure.</p> <p>In the case of liquids, we're relating them to water is at its densest, which is 39.2 degrees Fahrenheit. You may have noticed that ice cubes float in water. That's because...
