2. Alveolar gas equation - Wikipedia

   en.wikipedia.org/wiki/Alveolar_gas_equation

   The alveolar gas equation is the method for calculating partial pressure of alveolar oxygen ( pAO2 ). The equation is used in assessing if the lungs are properly transferring oxygen into the blood. The alveolar air equation is not widely used in clinical medicine, probably because of the complicated appearance of its classic forms.

3. Ideal gas law - Wikipedia

   en.wikipedia.org/wiki/Ideal_gas_law

   This form of the ideal gas law is very useful because it links pressure, density, and temperature in a unique formula independent of the quantity of the considered gas. Alternatively, the law may be written in terms of the specific volume v, the reciprocal of density, as. It is common, especially in engineering and meteorological applications ...

4. NACA airfoil - Wikipedia

   en.wikipedia.org/wiki/NACA_airfoil

   "a=" followed by a decimal number describing the fraction of chord over which laminar flow is maintained. a=1 is the default if no value is given. For example, the NACA 65 4 -415, has the minimum pressure placed at 50% of the chord, has a maximum thickness of 15% of the chord, design lift coefficient of 0.4 and maintains laminar flow for lift ...

5. Henry's law - Wikipedia

   en.wikipedia.org/wiki/Henry's_law

   Henry's law. In physical chemistry, Henry's law is a gas law that states that the amount of dissolved gas in a liquid is directly proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. It was formulated by the English chemist William Henry, who studied the topic in the early 19th century.

6. Schwarzschild's equation for radiative transfer - Wikipedia

   en.wikipedia.org/wiki/Schwarzschild's_equation...

   In the study of heat transfer, Schwarzschild's equation[ 1][ 2][ 3] is used to calculate radiative transfer ( energy transfer via electromagnetic radiation) through a medium in local thermodynamic equilibrium that both absorbs and emits radiation. The incremental change in spectral intensity, [ 4] ( dIλ, [W/sr/m 2 /μm]) at a given wavelength ...

7. Per-unit system - Wikipedia

   en.wikipedia.org/wiki/Per-unit_system

   Per-unit system. In the power systems analysis field of electrical engineering, a per-unit system is the expression of system quantities as fractions of a defined base unit quantity. Calculations are simplified because quantities expressed as per-unit do not change when they are referred from one side of a transformer to the other.
