Air density
Air density refers to the mass per unit volume of air at a certain temperature and pressure, which is the air density. The density of air is related to temperature, altitude and other factors. The higher the altitude, the lower the density of air. Therefore, many people lack oxygen on the plateau. The air density we generally use refers to the air density of about 1.29kg/m3 under the absolute standard index of 0 ℃.
Calculation formula of air density
Calculate the air density & Rho; The formula is & Rho= (m1-m0) / V, M1 in the formula is the total mass of the density bottle and air, V is the corresponding volume, and M0 is the mass of the density bottle. （KongQiMiDuShiDuoShao）
