So Cd probably is less. An argument can be made that Cd could be accounted for by conventional fluid mechanical Reynold's number calculations related to drag coefficient (Cd). Richard Saam |

In the field of waste water, drinking water and
sanitation there is the concept of orthokinetic flocculation which is generally mathematically expressed by shear = sqrt(Power/(viscosity x Volume)) Given a tank (with "Volume" cm^3) filled with water (with absolute "viscosity" g/(cm sec)) (momentum transferred per surface area) and this water containing particles, a "Power" (erg/sec) (motor driven impeller) is introduced to provide "shear" (/sec) (dv/dx) within the water. v2 - Particle 2 / / ^ / | / x / v1 - Particle 1 Particle 1 and Particle 2 move at different velocities in the shear (v2-v1)/delta_x or dv/dx Proper selection of shear ensures that particles remain suspended in the fluid and if they aggregate or remain separate. It is interesting to note that shear (dv/dx) has units of /time. This is the same unit as the Hubble constant in cosmology. Could the cosmos (volume) be observed as an orthokinetic fluid medium with vacuum energy density having a viscosity such that observed Hubble "shear" is congruent with galactic mass distribution with the universe?
