Freestream Dynamic Pressure in Fundamentals of Inviscid and Incompressible Flow Formulas

Freestream Dynamic Pressure is the kinetic energy per unit volume of fluid at some distance from the body where the density and velocity are freestream values. And is denoted by q_∞. Freestream Dynamic Pressure is usually measured using the Pascal for Pressure. Note that the value of Freestream Dynamic Pressure is always positive.
