Imp: Do I need to assume mean velocity in the dynamic pressure?,<\/strong> for example, if we have water, Density: 1000kg\/m3 and Velocity: 5m\/s (<strong>assume<\/strong>) gives me Dynamic Pressure of 12500 Pa then<strong> I get the Stagnant Press=101325+12500=113825Pa?<\/strong> I get the following graph for the residual?
