This formula assumes uniform flow conditions within the entire cross-sectional area, without any friction losses near to surfaces.

Q Volume flow rate v Flow velocity A Cross-sectional area n.b. Cross-Sectional AreaĮnter the size of the area perpendicular to the direction of flow. The volumetric flow rate formula used by this calculator is: Q v Flow Velocity MeasuredĮnter the speed at which the substance is moving. The volumetric flow rate formula used by this calculator is: For each new calculation a unique conversion scale will be generated for the range of flow velocities and volumetric flow rates with the cross sectional area specified. (or if you know density directly) cfm volumetric flow rate lb/hr mass flow. This tool will calculate the volumetric flow rate in any units from the specified velocity of a substance flowing through a defined cross-sectional area.

Calculate cross-sectional area of rectangular shaped duct (velocity of air) squared, or velocity sqrt (2Pressure/density) and flow rate equals velocity times cross sectional area, so cfm area of pipe sqrt (2.

Calculate cross-sectional area of circular pipe or duct.

Calculate flow velocity from a given volume flow rate and area.

Calculate flow area from volume flow and flow speed.

Most exhaust fans should have an airflow reading of somewhere between 40 and 60 cfm to operate efficiently. Sorry, a graphic could not be displayed here, because your browser does not support HTML5 Canvas. The rough airflow measurements for different inches are: 25 cfm for 1.5 inches (3.8 cm) 35 cfm for 2 inches (5.1 cm) 48 cfm for 2.5 inches (6.4 cm) CFM stands for cubic feet per minute, which is how airflow is measured. WitrynaStep 1: Convert Customer Gas Flow Rate unit of measure to a standard unit of measure for air flow (SCFM or SCCM).
