The discussion clarifies the relationship between gage pressure and absolute pressure in fluid mechanics, specifically through the equation p(gage) = p - pa. Here, P represents absolute pressure, while Pa denotes atmospheric pressure. Gage pressure is defined as the pressure reading that excludes atmospheric pressure, which is typically around 101 kPa. This distinction is crucial for accurate pressure measurements in fluid systems.
PREREQUISITESThis discussion is beneficial for students studying fluid mechanics, engineers working with pressure systems, and anyone needing to understand the distinctions between gage and absolute pressure in practical applications.
