ve Q3. Péclet number - We've seen the Péclet number Pé =, as a useful metric to determine if stirring (Pé > 1) is more efficient than diffusion (Pé < 1) for mixing solutions. "Stirring" here can designate any process which applies a force on the molecules, resulting in a velocity v. a) Show that the Péclet number, like the Reynolds number, is unitless. Let's think about why scale (l) matters for mixing. λ-DNA, a DNA polymer containing 48,502 base pairs, has a diffusion coefficient of D 6.4 x 10-13 m² s-¹. Under an electric field of 1 V/m, we can expect λ-DNA to reach a terminal velocity of 30 nm/s. = b) Find the Péclet number for a system of dimension of l = 10 cm. This corresponds to the scale of most benchtop instruments used to manipulate or separate biomolecules.

Q3. Péclet number - We've seen the Péclet number Pé : vl as a useful metric to determine if stirring (Pé > 1) is more efficient than diffusion (Pé < 1) for mixing solutions. "Stirring" here can designate any process which applies a force on the molecules, resulting in a velocity v. a) Show that the Péclet number, like the Reynolds number, is unitless. Let's think about why scale (l) matters for mixing. A-DNA, a DNA polymer containing 48,502 base pairs, has a diffusion coefficient of D = field of 1 V/m, we can expect 1-DNA to reach a terminal velocity of 30 nm/s. 6.4 x 10-13m²s-1. Under an electric b) Find the Péclet number for a system of dimension of l = 10 cm. This corresponds to the scale of most benchtop instruments used to manipulate or separate biomolecules.
