In a confined space, leaking hydrogen can accumulate and reach a flammable concentration. Any gas other than oxygen is …
WebThe formula to measure density is density = mass/volume. Air density at sea level is, on average, around 1.225 kg/m3. That will go up or down depending on what all is in the air. If it is humid, for example, the H20 molecules are denser, which will cause the total air density to be slightly higher. Air pressure/weight and air density are related.
