WebTo calculate the air change in a room, the airflow is measured (CFM) and multiplied by 60 minutes per hour. It is then divided by the volume of the room you wish to measure (in cubic feet): Air Changes / hr = (CFM x 60 minutes) / Volume of the room (cubic feet) WebThe air flow meter measures the flow velocity according to the hot wire principle. This guarantees a particularly compact design. In addition to the flow rate, the air flow meter …

It includes the total electrical power taken from the mains by all the supply and exhaust fans of the entire building (the exhaust can also be a roof extractor) divided by the treated air flow. The divider is always the higher airflow (inlet or outlet).
WebThis resistance to flow is defined by an equation of the form: P = K p Q n (eq.4) Where P = pressure drop inches of water (inches w.g.). Q = airflow in cu. ft/min (CFM). K = a constant determined by the characteristics of the system. n = a constant depending upon the type of flow. p = density of air in lb. per cubic foot.
