Enter actual inlet temperature entering the blower in degrees Fahrenheit. SCFM doesnt only tell us what the volume of the air is (V), it also specifies what is the pressure (P), amount of gas (n), and temperature (T). If you have any other questions, you can use the comments below and well try to help you out as best we can. SCFM differs from CFM mainly in that SCFM has these variables fixed. Take the calculated CFM and compare to the compressor output. ; Related Documents . However, the same volume of air can have different temperatures, pressure, and humidity. SCFM always has a standard pressure level of 14.7 psi. Divide the tank volume by 7.48 (7.48 equals the number of gallons in one cubic foot.) If the compressor loads at 80 PSI and unloads at 120 PSI, this equals a 40 PSI difference (also known as differential pressure). SCFM to CFM Calculator. Standard Pressure (Ps) There is no standard pressure condition in CFM. SCFM Calculator: Determine the number of gallons that make up the air compressor's tank; Calculate the value by dividing 7.48 by the amount; Turn off the air compressor to let out some pressure; The air compressor needs to be refilled now. Insert flow, ACFM. To convert psi to scfm, you need to know the conversion factor. If you dont know which one to choose, give us a call and we will help to walk you through what your system may need. The two types of flow rate measurement are mass flow measured by weight, often used in chemical process industries, and volumetric flow measured in cubic feet per minute (cfm) (liters per minute). But liters are a measure of volume and cfm a measure of volumetric flow, volune/time. Outside of that range, you need an equation of state calculator to determine compressibility.

That is airflow at 1 atm (14.7 psi) pressure and 68F temperature (or 293K). The majority of air tools made for general use with portable air compressors will generally require 0 to 5 cubic feet per minute (CFM) at 70 to 90 pounds per square inch (PSI), while larger tools connected to stationary systems, the requirements usually exceed 10 CFM at 100 to 120 psi. If we have SCFM, we can convert them to CFM, if we know at what pressure and temperature these CFMs will be. The formula for converting SCFM to ACFM is as follows: ACFM = SCFM [Pstd / (Pact - Psat )] (Tact / Tstd) Where: ACFM = Actual Cubic Feet per Minute. SCFM refers to "standard cubic feet per minute" or the given flow rate of air at standard room temperature and pressure. This might look like a daunting equation, but its quite easy to use.
