The density of air varies with temperature and pressure. The volume flow rate of a fluid is defined as the volume of fluid that passes through a given cross-sectional area per unit of time. Or can you convert the capacity in SCFM to lbs/hr and compare to your calculated load (API 521 calculation gives lbs/hr). ACFM. 5 psia) Pa = Atmospheric pressure, psia ppm = Partial pressure of moisture at atmospheric temperature RH = Relative humidity Ta = Atmospheric Temperature, °F Ts = Standard Temperature, °F (CAGI and ISO use 68 °F) (CAGI and ISO standard is at zero RH) Energy Efficiency: Evaluating SCFM can also indicate how efficiently an air compressor operates, allowing users to make informed choices to save on energy costs. 7+psig) If you read the gas flow at 100 SCFM at a temperature of 90 degrees F and a pressure of 40 psi, your ACFM flow is: 100* Calculate ACFM to SCFM and SCFM to ACFM. The latter refers to the pounds per square inch of air pressure. To convert SCFM to actual flow (ACFM) at any other pressure and temperature conditions, the basic formula used is: ACFM = SCFM X Ps – (RH s X PV s) X T a X P b P b – (RH a X PV a) T s P a Where: P DCFM, SCFM and ACFM Home Engineering Information DCFM, SCFM and ACFM. Option 2: Even though we realize the actual density at the traverse was not standard, calculate using the standard density. "SCFM" is really a mass flow measurement. In this example, we will find what volume of gas 2,500 scfm represents at 200 psig and 250 deg F. We assume you are converting between cubic foot/minute and litre/minute. 696 psia and 60 degF conditions. Check the conditions used for CFM measurements: If CFM is listed, make Convert ACFM to SCFM SCFM = ACFM x (Pounds Per Square Inch Gauge + Atmospheric Pressure) x 528 (Temperature of Air Inlet + 460) x Atmospheric Pressure SCFM = ACFM x PSIG + 14. SCFM – ACFM EXAMPLE 1 – Normal Day For this example we will reference a 30-hp compressor operating at 1020 rpm, and use it in Cartagena and Medellin to demonstrate how SCFM and ACFM should be used. More information from the unit converter. Alternative Flow Units. Some people even use SCFM and ACFM interchangeably. For math, science, nutrition, history VACUUM PUMP SIZING CALCULATORS Understanding how to convert different units of measurement can be difficult, but it’s a critical skill to have. The calculation is based on standard conditions of 68°F, 36% relative humidity (RH) and 14. 94 a, 6% loss at full load — a Pressure varies inversely with SCFM, so if your PSI is 120, your SCFM will be lower than if your PSI is 80.
