SCFM is the amount (volume) of air that would happen if your air were at room temperature, and atmospheric pressure (0ft above sea level, 14.7psi). CFM (cubic feet per minute) is the amount (volume) of air that happens at the specific temperature and pressure. example: if you have a balloon that happens to be one cubic foot, and you are inside of a very hot, very high pressre room. when you walk out of the hot room, the flow rate is 1CFM, but because it is a balloon, when you take it outside the room it suddenly expands as it adjusts to outside (close to standard) conditions. So your balloon may be 3 or 4 SCFM. The two are interchangable, but when working in an industry that used flow rates heavily, it's much easier to note SCFM, because it has the added bonus of telling you temperature and pressure along with flow rate.

How much is 400scfm at 116.0302 PSI in cfm?
To convert from 400 scfm at 116.0302 PSI to cfm, you can use the ideal gas law equation. Assuming standard conditions of 14.7 PSI and 60°F, you can adjust the volume flow rate from the given conditions to standard conditions using the ideal gas law. Applying this equation will give you the equivalent flow rate in cfm at standard conditions.
What do sfm stands for in hvac?
CFM stands for "cubic feet per minute" and is a measure of the volume of air moving through a fan or duct. SCFM is "standard cubic feet per minute," usually taken to mean CFM of "standard air," air at 68 degrees F and atmospheric pressure at sea level.The HVAC Veteran
How do you calculate sensible heat if you know cfm and temperature difference?
To calculate sensible heat, you can use the formula: Sensible Heat (BTU/hr) = 1.08 x CFM x Temperature Difference (°F). Just multiply the CFM value by 1.08 and then by the temperature difference in Fahrenheit to get the sensible heat in BTU per hour.
How many btuh in cfm?
To convert CFM (cubic feet per minute) to BTU/hr (British thermal units per hour), you can use the formula: BTU/hr = CFM × ΔT × 1.08, where ΔT is the temperature difference in degrees Fahrenheit between the inlet and outlet air. The constant 1.08 is derived from the specific heat of air and the conversion factors of CFM to BTU. Therefore, the exact number of BTU/hr from CFM depends on the temperature difference you are considering.
How do you get cfm with a manometer?
To calculate CFM (cubic feet per minute) using a manometer, measure the pressure difference across a restriction in the airflow system. Use the manometer reading and the area of the restriction to determine the velocity pressure. Then, use the velocity pressure to calculate the airflow in CFM using the formula CFM = (Velocity Pressure * Area of the Restriction) / 4005.
How do you calculate air handling unit tonnage?
To calculate the tonnage of an air handling unit (AHU), you can use the formula: Tonnage = (CFM × ΔT) / 24,000, where CFM is the airflow in cubic feet per minute and ΔT is the temperature difference in degrees Fahrenheit between the supply and return air. The factor of 24,000 is used because one ton of cooling is equivalent to 12,000 BTUs per hour, and the formula converts CFM and temperature difference into a tonnage value. Ensure that the CFM and temperature difference are accurately measured for precise tonnage calculations.
