The discussion centers on the definitions and implications of static pressure and dynamic pressure in fluid mechanics, particularly in the context of Bernoulli's principle. Participants emphasize that static pressure is the only "real pressure" that can be felt, while dynamic pressure represents kinetic energy per unit volume. The conversation highlights the importance of distinguishing between these terms to avoid misconceptions about pressure behavior in moving fluids. The consensus is that while static pressure is crucial for understanding force on surfaces, dynamic pressure has practical applications in measuring drag and flow velocity.

Missed an edit, my previous post is correct now. The point was that dynamic, impact, or stagnation pressure can refer to either compressible or incompressible flow.boneh3ad said:Right, so he was asking what he would call the two terms on the right hand side that add up to stagnation pressure. You only quoted the one term, and the term you quoted was the dynamic pressure term.
