The air density value in the handbook of physical properties of chemicals and chemical engineering products is incorrect
Thread Content
In the table below, the density of air at 280K (6°C) and 0.1 Mpa is 0.1245 kg/m3. However, the density of air at 0 degrees Celsius and standard atmospheric pressure is 1.29 kg/m3, which is an order of magnitude different from the value in the table. Why is this?
It is guessed that the pressure shown in the image should be in bars, rather than MPa. Look, at 1.0 – it’s pretty much the same as normal pressure
In this way, the two can correspond to each other
