    VAV K-Factor

    Is there an equation between K-Factor and Velocity Pressure, or it varies with different VAV Manufactures?

    I'm not sure what exactly you are looking for, but K-factor is something that usually refers to the correction for free area of diffusers and registers.

    Velocity pressure is a value resulting from the relationship between total pressure and static pressure that is used in calculations when you are determining airflow volume.
