vl 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) Find the Péclet number for a system of dimension of l = 10 μm. This corresponds to the scale over which most cellular processes occur. b)Find the scale f for which diffusion is just as efficient as electric field for displacing λ-DNA.
