Compressed air flow rate calculator Total Air Compressor Flow Rate (CFM) is the flow rate of the air compressor in cubic feet per minute. The number of compressors and their mutual size are determined principally by the required degree of flexibility, control Compressor Speed Calculator. Tweet; Company Info. Suppose you have an air flow rate of 120 CFM moving through a pipe with an inner diameter of 4 inches. 15/(273. For air k=1. The relation between the two volume rates of flow is (note that the simplified formula above does not account for humidity). This should be then: max flow rate = (number of actuators opening at once) x (volume per actuation) / (smallest actuation time) = (20)(0. This calculator makes it possible to obtain the values of maximum and minimum air flow rate of a work cycle, as well as the total air consumption of the pneumatic circuit per cycle.
