Equation relating temperature and pressure
WebMay 13, 2024 · So if the pressure doubled, the temperature ratio is 1.219. The key point here is that we have a function that relates the temperature change to the pressure change during a compression process. We can use the equation of state to derive the relation between the volume change and the pressure change. The equation of state is: p * v = … WebDec 9, 2024 · For dry air (namely, air with the usual mix of gases, except no water vapor), the ideal gas law is: (1.18) P = ρ ⋅ ℜ d ⋅ T. where ℜ d = 0.287053 kPa·K –1 ·m 3 ·kg –1 = 287.053 J·K –1 ·kg –1 . ℜ d is called the gas constant for dry air. Absolute temperatures (K) must be used in the ideal gas law. The total air pressure P ...
