The formula to calculate the weight of air (W) is:
\[ W = V \times D \]
Where:
Air weight refers to the mass of air within a given volume. It is a function of air density, which can vary based on temperature, pressure, and humidity. Understanding the weight of air is important in various scientific and engineering applications, including meteorology, HVAC (heating, ventilation, and air conditioning), and aircraft design.
For example, if the volume of air (V) is 50 cubic meters and the density of air (D) is 1.225 kg/m³, the weight of air (W) can be calculated as follows:
\[ W = 50 \times 1.225 = 61.25 \]
So, the weight of air for a volume of 50 cubic meters at a density of 1.225 kg/m³ is 61.25 kg.
Definition: The specific weight of air is the weight per unit volume of air.
Formula: \( \gamma = \frac{W}{V} \)
Example: \( \gamma = \frac{1.2}{1} \)
Definition: This calculator determines the weight of compressed air based on its volume and density.
Formula: \( W = \rho V \)
Example: \( W = 1.5 \times 2 \)
Definition: Calculating the pounds of air involves determining the weight of air in pounds based on its volume and density.
Formula: \( W = \rho V \)
Example: \( W = 0.075 \times 100 \)
Definition: This calculator determines the chargeable weight of air for shipping purposes.
Formula: \( \text{Chargeable Weight} = \max(\text{Actual Weight}, \text{Volumetric Weight}) \)
Example: \( \text{Chargeable Weight} = \max(50, 60) \)
Definition: The unit weight of air is the weight of air per unit volume.
