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.
