What components make up total pressure in low-speed airflow?

Total pressure in low-speed airflow is fundamentally composed of static pressure and dynamic pressure.

Static pressure refers to the pressure exerted by the weight of the fluid (air, in this case) at rest, which acts equally in all directions. It is a key parameter in determining the aerodynamic performance of an aircraft.

Dynamic pressure, on the other hand, is a measure of the kinetic energy per unit volume of the airflow and is calculated based on the velocity of the airflow. It reflects the impact of the fluid's motion and is essential for understanding how aircraft generate lift and experience drag.

When combined, static and dynamic pressure form the total pressure, which is crucial for various calculations in aerodynamics, such as determining lift and understanding airflow characteristics around the aircraft.

The other options do not accurately represent the components of total pressure. Static and dynamic temperature, dynamic lift and drag, and static lift and weight refer to different concepts in aerodynamics and do not constitute total pressure.
