What is static pressure?

Static pressure is the level of pressure a fluid exerts when it is not moving or is at rest. It is one of the key components in the study of fluid dynamics and is important in various engineering applications, such as in HVAC systems, aircraft design, and fluid mechanics.

In a fluid system, static pressure is the pressure that is exerted by the fluid on the walls of the container or duct that it is contained in. It is usually measured in units of pascals (Pa) or pounds per square inch (psi). In a closed system, static pressure remains constant as long as there are no changes in the volume or temperature of the fluid.

Static pressure is important in determining the flow rate of a fluid in a system, as it affects the resistance the fluid encounters as it moves through pipes, ducts, or other channels. It is also used in conjunction with dynamic pressure to calculate total pressure in a fluid system.

Overall, static pressure plays a crucial role in the design and operation of various engineering systems and is crucial for ensuring the efficient and safe transport of fluids.
