WebAug 18, 2024 · The key to solving this equation is Boyle’s Law: for a given quantity of gas, it has the form P V = c o n s t., but notice that means that if the pressure of the gas is doubled, the gas is compressed into half the space, so its density is also doubled. So an alternative way to state Boyles law is. (1.2.9) ρ ( h) = C P ( h) where C is a ... WebTechnical Atmosphere (at or kgf/cm 2) The technical atmosphere (at) is the metric equivalent of psi, and is measured in kilogram-force per square centimeter. If you followed by back-of-the-envelope approximations from psi, you’d guess that the atmospheric pressure in technical atmospheres is about 1 kgf/cm 2. Actually, 1 at is 0.97 atm.
