In this business, we deal with pressures, pressure drops, flows and velocities all the time. For all that familiarity, you'd think we could visualize what one of these measurements means in terms of the others. Unfortunately, most of us can't. Mentally, we have a hard time relating the velocity of a moving airstream to its velocity pressure, and we usually underestimate, by a huge margin, the force exerted on a surface by a static pressure. Maybe we just don't use the right terms to fix the ideas in our heads. Let's try out some non-standard ways of looking at the subject.
