The airflow price isn't the exact same thing as velocity. Velocity refers to the amount floor air handles relative to time. Meanwhile, the airflow charge highlights air output since it relates to time.
We’re gonna deal with the equal friction strategy in this instance because it’s the commonest strategy utilized for business HVAC systems and its fairly simple to adhere to.
