To use a CFM (cubic feet per minute) calculator to determine airflow needs for a room, know variables such as the volume of the room and the number of times the air changes per hour from the fan/ventilation system and apply them to a formula. CFM is an engineering calculation used to find the heatin


The equation for calculating CFM, or cubic feet per minute, is CFM = fpm times area, where area is expressed as square feet and fpm represents feet per minute. This measurement is used for calculating air volume velocity and measuring the rate of ventilation in heating and cooling operations.


Fan size is expressed as CFM capacity and is determined by dividing the area of a room by the number of minutes per hour needed to replace the volume of air. CFM indicates cubic feet per minute and indicates the amount of circulation necessary to properly ventilate a room.


A duct calculator measures air velocity by using a formula in which air flow is a variable expressed in cubic feet per minute, or CFM. Heating, ventilation and air conditioning professionals commonly use duct calculators.


Some good ways to measure CFM include using a measurement from an air balancing hood and measuring the airflow with an anemometer. CFM stands for cubic feet per minute, and is used to measure how much air a ventilation system is capable of pushing.


To calculate the minimum cubic feet per minute rating needed for an exhaust fan, multiply the bathroom's length, width and height, and then multiply that result by 0.13. The final answer is the minimum CFM rating for the fan.


In science, cfm stands for chlorofluoromethane, and is more commonly known as Freon 31. Chlorofluoromethane is any of a series of gaseous or volatile methanes replaced by chlorine and fluorine and having little or no hydrogen.


To calculate the CFM (Cubic Feet per Meter) of an air compressor is the same as calculating the output of the compressor. Calculating CFM begins with looking at the specifications of the compressor to find the volume of the tank. The next step is checking technical specifications of the sheet to fin


A CFM file is a ColdFusion Markup file and is a simple text file, meaning it can be opened with any text editing software. CFM files are used and opened by Adobe ColdFusion, a commercial Web application development platform. However, you have to buy this software.


A cfm conversion is a change in units from cfm to other units, such as cfm to cubic kilometer per hour, cfm to cubic yard per minute, cfm to cubic mile per day or cfm to cubic millimeter per second. Units should be of the same category, volume flow rate.
