1 cubic meter/second is equal to 2118.8799727597 cfm, or 2118.8799727597 cubic foot/minute. metres squared, grams, moles, feet per second, and many more! You will find the calculator (with calculated chart) below the explanation of SCFM vs CFM . Table 1 gives the numerical values for 29. . How do you calculate air flow in pressure? Just insert this in the equation (6 inches = 0.5 ft) like this: CFM (6 Round Duct) = 500 FPM * 3.14 * (0.5 Ft / 2)2 = 98.15 CFM. One ton equals 12,000 BTUs, so if a house or office needs 24,000 BTUs, it will take a 2-ton HVAC unit. To avoid doing these calculations by hand, we have prepared 2 calculators (1st calculator for round ducts, 2nd calculator for rectangular ducts) that do all this math automatically. Example: What is the CFM of air moving through an 8 10 inch duct if the air velocity is 800 FPM? This FPM to CFM calculator can be used to convert feet per minute to . You can check this list to get an idea of how much CFM the best air purifiers can produce (for reference). In this round duct, 500 FPM is equal to 98.15 CFM. Math is the study of numbers, space, and structure. W2 Wire Thermostat Wiring (2nd Stage), Thermostat Wire Color Codes For 3-8 Wire Thermostats (Color-By-Color), How Many Therms Of Gas Per Month Is Normal? CFM is a 'ft 3 per minute' unit. Air velocity (distance traveled per unit of time) is usually expressed in Linear Feet per Minute (LFM). It might sound a bit strange since cubic feet as a unit of volume and not mass or weight. 825 CFM. Then click the Convert Me button. 1 ft3/min = 28.316846999 L/min. I can help you with any mathematic task you need help with. Amazing app! - free apps for offline use on mobile devices. A higher CFM is always better for your kitchen fan. 1 Cubic foot per hour is approximately 0.000 007 865 790 72 cubic meters per second. A standard measurement of airflow that indicates how many cubic feet of air pass by a stationary point in one minute. cfm to acre foot/hour Amazing app that can solve almost all the problems you enter into it. Math can be tough to wrap your head around, but with a little practice, it can be a breeze! If you know the ACH you need, you can use the cfm calulator below instead. The yield is 1200 cubic feet per minute. The cubic foot per minute (symbol: CFM) is a the unit of volumetric flow rate equal to that of a cubic foot moving each minute.It is equal 0.000471947 m 3 /s. Lithium, Deep Cycle (+ Calculator), Natural Gas MMBTU To m3 And m3 To MMBTU Calculator + Chart, BTU/h To Horsepower Calculator + BTU/h To HP Chart (To 72,000 BTU/h), Horsepower To BTU/Min: Convert HP To BTU Per Minute (Calc + Chart), HP To BTU/hr: Horsepower To BTU For A/C (Calculator + Chart). math is the study of numbers, shapes, and patterns. Here is the full calculated table from 1 FPM to 5000 FPM converted to CFM for 4-inch, 6-inch, 8-inch, and 10-inch circular ducts: Using this chart, you can quite easily determine how many CFM can these 4, 6, 8, and 10-inch diameter round ducts carry. window.jQuery || document.write('
