SUMMARY
The discussion centers on the interpretation of pressure as a momentum flux, specifically through the equation: pressure = (1/3) * number density * volume * momentum. Participants clarify that pressure is defined as force per unit area (N/m²) and that momentum flux is expressed as (kg·m/s) / (m²·s). The conversation highlights the need for consistency in units, suggesting that "volume" in the equation should likely be "velocity" to maintain dimensional accuracy.
