  2. 2,5-Dichlorophenol - Wikipedia

    en.wikipedia.org/wiki/2,5-dichlorophenol

    2,5-Dichlorophenol (2,5-DCP) is a chlorinated derivative of phenol with the molecular formula Cl 2 C 6 H 3 OH. References. Cited sources. Haynes, William M., ed ...

  3. Nitrogen washout - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_washout

    The following describes a single-breath nitrogen test: A subject takes a breath of 100% oxygen and exhales through a one-way valve measuring nitrogen content and volume. A plot of the nitrogen concentration (as a % of total gas) vs. expired volume is obtained by increasing the nitrogen concentration from zero to the percentage of nitrogen in ...

  4. Dichlorophenol - Wikipedia

    en.wikipedia.org/wiki/Dichlorophenol

    Chemical structure of 2,4-dichlorophenol. Dichlorophenols (DCPs) are any of several chemical compounds which are derivatives of phenol containing two chlorine atoms. There are six isomers:

  5. Rideal–Walker coefficient - Wikipedia

    en.wikipedia.org/wiki/Rideal–Walker_coefficient

    It is the ratio of the dilution of the disinfectant that kills a microorganism to the dilution of phenol that kills the organism in the same time under identical conditions. The Rideal–Walker coefficient determines the phenol coefficient utilizing the method (test) described by English chemists Samuel Rideal (1863–1929) and J. T. Ainslie ...

  6. Standard temperature and pressure - Wikipedia

    en.wikipedia.org/wiki/Standard_temperature_and...

    The molar volume of gases around STP and at atmospheric pressure can be calculated with an accuracy that is usually sufficient by using the ideal gas law. The molar volume of any ideal gas may be calculated at various standard reference conditions as shown below: V m = 8.3145 × 273.15 / 101.325 = 22.414 dm 3 /mol at 0 °C and 101.325 kPa

  7. Spirometry - Wikipedia

    en.wikipedia.org/wiki/Spirometry

    The tracer gas is analyzed simultaneously with CO to determine the distribution of the test gas mixture. This test will pick up diffusion impairments, for instance in pulmonary fibrosis. [ 22 ] This must be corrected for anemia (a low hemoglobin concentration will reduce DLCO) and pulmonary hemorrhage (excess RBC's in the interstitium or ...

  8. Mean inter-particle distance - Wikipedia

    en.wikipedia.org/wiki/Mean_inter-particle_distance

    Note that since the particles in the ideal gas are non-interacting, the probability of finding a particle at a certain distance from another particle is the same as the probability of finding a particle at the same distance from any other point; we shall use the center of the sphere.

  9. Viscosity models for mixtures - Wikipedia

    en.wikipedia.org/wiki/Viscosity_models_for_mixtures

    The dilute gas viscosity contribution to the total viscosity of a fluid will only be important when predicting the viscosity of vapors at low pressures or the viscosity of dense fluids at high temperatures. The viscosity model for dilute gas, that is shown above, is widely used throughout the industry and applied science communities.
