Mechanical Engineering Question:
How can you convert air mass to air volume?
Answer:
Mass = density * volume.
Air density is p/RT, where R is the gas constant for air (287 J/kg-K), T is the absolute temperature, and p is the pressure, equal to 101325 Pa at sea level.
At sea level and room temperature, the density of air is
rho 101325 N/m2/ (287 N-m/ (kg-K)*293 K
or about a) 2 kg/mc)
