| Grain Drying with Natural Air Calculator to determine conditions for drying grain. |
| 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). |
| Balloon lifting force Online calculator for solving problems related to balloon lifting force. It allows you to find the mass of the balloon shell, or the mass of the payload, or the required hot air temperature, or the volume of the balloon, from other known values. |
| Density of air as a function of pressure and temperature This online calculator calculates the air density value for a given pressure and temperature using the Mendeleev-Clapeyron equation for an ideal gas. |
