    Fugacity and BCF relate to each other in the following equation: = [6] where Z Fish is equal to the Fugacity capacity of a chemical in the fish, P Fish is equal to the density of the fish (mass/length 3), BCF is the partition coefficient between the fish and the water (length 3 /mass) and H is equal to the Henry's law constant (Length 2 /Time 2) [6]

  3. Tris(pentafluorophenyl)borane - Wikipedia

    en.wikipedia.org/wiki/Tris(pentafluorophenyl)borane

    Tris(pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C 6 F 5) 3 B. It is a white, volatile solid. It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC 3 core is planar .

  4. Cooling load temperature difference calculation method

    en.wikipedia.org/wiki/Cooling_load_temperature...

    The equations for the use of the data retrieved from these tables are very simple. Q= heat gain, usually heat gain per unit time. A= surface area. U= Overall heat transfer coefficient. CLTD= cooling load temperature difference. SCL= solar cooling load factor. CLF= cooling load factor. SC= shading coefficient.

  5. High-temperature operating life - Wikipedia

    en.wikipedia.org/wiki/High-temperature_operating...

    High-temperature operating life (HTOL) is a reliability test applied to integrated circuits (ICs) to determine their intrinsic reliability. This test stresses the IC at an elevated temperature, high voltage and dynamic operation for a predefined period of time. The IC is usually monitored under stress and tested at intermediate intervals.

  6. Mean free path - Wikipedia

    en.wikipedia.org/wiki/Mean_free_path

    Mean free path. In physics, mean free path is the average distance over which a moving particle (such as an atom, a molecule, or a photon) travels before substantially changing its direction or energy (or, in a specific context, other properties), typically as a result of one or more successive collisions with other particles.

  7. Solder fatigue - Wikipedia

    en.wikipedia.org/wiki/Solder_fatigue

    Solder fatigue is the mechanical degradation of solder due to deformation under cyclic loading. This can often occur at stress levels below the yield stress of solder as a result of repeated temperature fluctuations, mechanical vibrations, or mechanical loads. Techniques to evaluate solder fatigue behavior include finite element analysis and ...

  8. Gibbs free energy - Wikipedia

    en.wikipedia.org/wiki/Gibbs_free_energy

    t. e. In thermodynamics, the Gibbs free energy (or Gibbs energy as the recommended name; symbol ) is a thermodynamic potential that can be used to calculate the maximum amount of work, other than pressure-volume work, that may be performed by a thermodynamically closed system at constant temperature and pressure.
