Air Flow Calibration
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).
Space object velocity
It calculates the circular orbital velocity, escape velocity and planetary system escape velocity for the given planet parameters.
Centripetal force
This online calculator calculates unknown parameter in the centripetal force formula, whether force, mass, radius or speed.
Сonstant acceleration
This online calculator solves problems with constant acceleration. It finds unknown parameter, either initial velocity, final velocity, time or acceleration, from known parameters.
