ixer Power to Achieve Complete Mixing It is desired to precipitate a protein in a solution with a density of 1.02 g/cm3 and kinematic viscosity of 0.012 cm2/s. The diffusion coefficient of the protein has been estimated to be 1.2 × 10−7 cm2/s. You need to select a mixer for this precipitation. To aid in this selection, plot as a straight line the dependence of the mixer power per solution volume (kW/liter) as a function of the time (s) to completely mix the solution for mixing times up to 100 s.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
