Total pressure (), also known as stagnation pressure, is the sum of the static pressure and dynamic pressure in a fluid flow. It represents the total energy per unit volume of a fluid stream, accounting for both the pressure energy and kinetic energy. Total pressure is a crucial parameter in fluid mechanics, particularly in analyzing fluid flow in pipes, ducts, and other engineering applications.
Where,
