Valve / port coefficient is non dimensional and is derived by multiplying a characteristic physical area of the port and by the bulk flow figures and comparing the result to an ideal orifice of the same area.

To minimise the effects of clogging and particle build-up a back flushing system must accommodate approximately 1-5 % of the bulk flow as back flush, operating at approximately 6-8 bar.
23.
If the acid's bulk flow out of the door is fast enough you might only have say the equivalent of half of it actually react to near completion with the lime and metal in the structure.

As the thoracic cavity contracts during expiration, the volume of the alveoli decreases and creates a pressure gradient between the alveoli and the air outside the body, and air moves by bulk flow down the pressure gradient.
25.
The distinction between internal and kinetic energy is hard to make in the presence of turbulent motion within the system, as friction gradually dissipates macroscopic kinetic energy of localised bulk flow into molecular random motion of molecules that is classified as internal energy.
26.
Hydrodynamic escape occurs if there is a strong thermal driven atmospheric escape of light atoms which through drag effects ( collisions ) also drive off heavier atoms a bulk flow type of escape of the upper atmosphere, a so-called " blowoff ".
27.
But still one can validly talk of a distinction between bulk flow and diffusive flow of internal energy, the latter driven by a temperature gradient within the flowing material, and being defined with respect to the local center of mass of the bulk flow.

Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct : cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the bulk flow and transport of metabolites between the organism and the external environment.
30.
These authors actually use the symbol to refer to total energy, including kinetic energy of bulk flow . ] " This usage is followed also by other writers on non-equilibrium thermodynamics such as Lebon, Jou, and Casas-V�squez, and de Groot and Mazur.
