Q3. Péclet number - We've seen the Péclet number Pé vl as a useful metric to D 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 (f) matters for mixing. 2-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 × 10-13m²s¬1. Under an electric b) Find the Péclet number for a system of dimension of e = 10 cm. This corresponds to the scale of most benchtop instruments used to manipulate or separate biomolecules. c) Find the Péclet number for a system of dimension of e to the scale over which most cellular processes occur. d) Find the scale l for which diffusion is just as efficient as electric field for displacing = 10 µm.

Name Chapter 20 Gases Boyle's Law A movable piston encloses 0.78 m³ of gas in a cylinder. The piston is then pushed downward, changing the volume of the gas to 0.36 m³ and the pressure to 2.8 kPa. What was the original pressure of the gas? 1. Read and Understand What information are you given? initial volume of the piston = V₁ = 0.78 m³ final volume of the piston = V₂ = 0.36 m³ final pressure of the piston = P2 = 2.8 kPa 2. Plan and Solve What unknown are you trying to calculate? original pressure of the piston = P₁ What mathematical equation can you use to calculate the unknown? Boyle's law: P₁V₁= P₂V₂ Rearrange the equation to solve for the unknown variable. P₂V₂ P₁₂₁= Substitute the values you know into the equation.
