In this case a 5-ton HVAC system at a nominal 2000 Cfm is split into 2 zones. For the sake of simplicity, the zones are assumed to be equal in load at 1000 Cfm each. ACCA Manual Zr defines this ratio of bypass Cfm versus system Cfm as the â Bypass Factor â (BPF) = 1000 / 2000 = .50 or 50%.n this case a 5-ton HVAC system at a nominal 2000 Cfm is split into 2 zones.

A poncho (Spanish pronunciation:; punchu in Quechua; Mapudungun pontro, blanket, woolen fabric) is an outer garment designed to keep the body warm. A rain poncho is made from a watertight material designed to keep the body dry from the rain.

cholo. A Mexican gangster. Other definitions say this is untrue, and that cholo means only means mestizo. However, since this is an urban dictionary where the idea is to communicate the colloquial, everyday meaning used in contemporary society, the correct meaning is mexican gangster. Cholo is a latino gangster (aka Vato Loco). Some Cholos may get their clothes from Dickies that are 2 sizes larger than what they would normally wear while buttoning only the top button. Cholos may invest in lowrider brand clothing and wear plaid flannel jackets during the winter.
