Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I need a formula to calculate how much power is wasted on different types of air filters. A typical application is a residential central air ductwork. A typical pressure drop is 0.1-0.2 inch wg. Typical volume passing through filters is 700-2000 cfm. A typical filter size is 2-3 sq. ft.

Your help is much appreciated in advance.
