For example, a 2-ton system might require a return duct with a size of around 16 inches in diameter. power droplet grounded A furnace can move only so much air. Of course the number of registers will effect the airflow of each supply. Example: 1,200 cfm blower with 12 - 6" supplies equal (approx.) 100 cfm each. Add more supplies and the amount of airflow gets reduced. Most homes have more supplies than the blower can fully supply.The air quantity (mass flow rate) required to satisfy the room load may be calculated from the following equation: RSH = m * Cp * ΔT. In volumetric terms air flow rate in cubic feet per minute (CFM) is estimated below: For air at ρ = 0.075 lbm/ft3 and Cp = 0.24. RSH = 0.075 * 0.24 * CFM x ΔT / 60.
