Description: In this short podcast episode, Bryan discusses the difference between mass flow and volume flow when referring to HVAC equipment processes. When you are confused as to whether you're dealing with mass or volume flow, think about the units. For example, cubic feet per minute (CFM) is a measure of volume because we're talking about cubic units. We care about the volume when we think about air mixing and velocity, but volume isn't much of an indicator of the actual cooling power. The mass or weight of the air matters more when we think about c...
