ACFM = (SCFM * (460 + gas temperature in Rankine)) / (530.67 * (gas pressure in psia)) In this formula: ACFM represents the Actual Cubic Feet per Minute, denoting the true flow rate of gas. SCFM refers to the Standard Cubic Feet per Minute, …HVAC Diffuser CFM Chart. Different sizes of HVAC diffusers can be used for the same airflow depending on the diffuser type. To give you a quick solution, below is the common diffuser sizes and their corresponded airflow. Airflow. Diffuser Size. Neck Size. 150 CFM. 2 ft …Feb 13, 2024 · The CFM to Tons Calculator is a handy tool used in the air conditioning and refrigeration industry to convert airflow rates, measured in cubic feet per minute (CFM), into cooling capacity, measured in tons. FPM (Rectangular Ducts) = CFM × 144 / (Duct Width (Inches) × Duct Height (Inches)) Basically, with rectangular ducts, we need to first multiply CFM by 144 (for inches to feet ….
