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).

Defines the mass and volume concentration of ethanol in the solution of two liquids with different levels of alcohol.

The calculator displays all the letters of a given language.

This calculator calculates the height or altitude difference between two points using barometric formula or barometric leveling method.
