Air Flow Calibration Calculator
This calculator is used to set the air flow rate through a grain bin equipped with an aeration fan. It assumes that the air flow can be controlled with baffles, spill gates or variable fan speed. It requires an air flow meter or anemometer. This calculator determines the air speed needed at the top collar of bin in order to achieve the desired air flow rate (CFM/bu Cubic Feet per Minute per bushel). Enter the values for the desired flow rate (CFM/bu), bin capacity (bu) and top collar diameter (ft). The output is the corresponding air speed (ft/min, km/hr & m/sec) required at the top collar of the bin. With the bin loaded with grain, measure the air speed at the top collar of bin by holding the air flow meter in the cross sectional plane of the top collar. Adjust the flow until the required air speed is achieved.
