2. Clearing denominators - Wikipedia

   en.wikipedia.org/wiki/Clearing_denominators

   Clearing denominators. In mathematics, the method of clearing denominators, also called clearing fractions, is a technique for simplifying an equation equating two expressions that each are a sum of rational expressions – which includes simple fractions .

3. 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.

4. Fraction of inspired oxygen - Wikipedia

   en.wikipedia.org/wiki/Fraction_of_Inspired_Oxygen

   Fraction of inspired oxygen ( FIO2 ), correctly denoted with a capital I, [ 1] is the molar or volumetric fraction of oxygen in the inhaled gas. Medical patients experiencing difficulty breathing are provided with oxygen-enriched air, which means a higher-than-atmospheric FI O 2. Natural air includes 21% oxygen, which is equivalent to FI O 2 of ...

5. NACA airfoil - Wikipedia

   en.wikipedia.org/wiki/NACA_airfoil

   t is the maximum thickness as a fraction of the chord (so t gives the last two digits in the NACA 4-digit denomination divided by 100). In this equation, at x = 1 (the trailing edge of the airfoil), the thickness is not quite zero. If a zero-thickness trailing edge is required, for example for computational work, one of the coefficients should ...

6. Fractional excretion of sodium - Wikipedia

   en.wikipedia.org/wiki/Fractional_excretion_of_sodium

   This is the numerator in the equation. The denominator is the total amount of sodium filtered by the kidneys. This is calculated by multiplying the plasma sodium concentration by the glomerular filtration rate (GFR) calculated using creatinine filtration. The flow rates then cancel out, simplifying to the standard equation: [1]

7. Q (number format) - Wikipedia

   en.wikipedia.org/wiki/Q_(number_format)

   Q (number format) The Q notation is a way to specify the parameters of a binary fixed point number format. For example, in Q notation, the number format denoted by Q8.8 means that the fixed point numbers in this format have 8 bits for the integer part and 8 bits for the fraction part. A number of other notations have been used for the same purpose.

8. Darcy friction factor formulae - Wikipedia

   en.wikipedia.org/wiki/Darcy_friction_factor_formulae

   Churchill equation [24] (1977) is the only equation that can be evaluated for very slow flow (Reynolds number < 1), but the Cheng (2008), [25] and Bellos et al. (2018) [8] equations also return an approximately correct value for friction factor in the laminar flow region (Reynolds number < 2300). All of the others are for transitional and ...

9. Small-angle approximation - Wikipedia

   en.wikipedia.org/wiki/Small-angle_approximation

   The sine and tangent small-angle approximations are used in relation to the double-slit experiment or a diffraction grating to develop simplified equations like the following, where y is the distance of a fringe from the center of maximum light intensity, m is the order of the fringe, D is the distance between the slits and projection screen ...
