Fan flow test
WebOct 1, 2024 · Generally, the power required by a fan increases as flow through the fan increases. With many airfoil and backward-curved or backward-inclined fans, however, power reaches a peak value and then decreases as flow increases. 2 This type of power curve is known as “non-overloading.” If the driving motor power is greater than the peak … WebHere we are measuring the performance of an air moving device such as a fan or blower. When the fan is operated in a free field, its airflow performance is high. As the impedance to airflow increases, the amount …
