1. See real gas or perfect gas or gas for further understanding .) 2. He'd be the perfect GA -- grad assistant, not geriatric assistant. 3. In addition to the mass, momentum, and energy conservation equations, a perfect gas equation of state: 4. Friedmann deduced this equation for the particular case of a perfect gas and published it in 1922. 5. The perfect gas theory is elegant and extremely useful for designing aircraft but assumes that the gas is chemically inert. 6. The theorem was first enunciated by Alexander Friedmann for the particular case of a perfect gas and published in 1922: 7. Ammonia gas is the best solution for the majority of interferences, but it is far for being the perfect gas . 8. This critical half-angle can be estimated using perfect gas theory ( this specific aerodynamic instability occurs below hypersonic speeds ). 9. Kinetic energy is simply the internal energy of the perfect gas and depends entirely on its pressure, volume and thermodynamic temperature. 10. Determining the thermodynamic state of the stagnation point is more difficult under an equilibrium gas model than a perfect gas model.
