The diffusion coefficient for horse hemoglobin in water is 1.26 × 10–10 m2 s–1 at 40 °C. The viscosity of water at 40 °C is 0.653 × 10–3 kg m–1 s–1. Estimate the radius of hemoglobin assuming the molecule to be spherical and obey Stokes’s law. Comment on the size of Hemoglobin to a corona virus unit which has a diameter of 120 nm.

Calculate the diffusion coefficient for the protein cytochrome c in aqueous solution assuming sphericity and using the Stokes-Einstein equation at 25degree C. The hydrodynamic radius is R =19.0 Angstroms. The viscosity of water is 1.00 cP = 0.00100 kg/m-s. D_cytc =__m^2/s. If the critical reaction distance is the sum of their radii, what value is expected for the Smoluchowski theory second order rate constant for a diffusion controlled reaction between two cytochrome c's? k_d = Lmol^-1s^-1 What would be the...

Water (density 998 kg/mº, dynamic viscosity 0.001 Pa s) is pumped between two reservoirs at a volumetric flow rate of 0.006 m/s through a 120-m long pipe of 5 cm diameter. The roughness ratio of the pipe is a/d = 0.001. There are some fittings and valves in the pipe system, as shown in Figure Q1. The loss coefficients of the valves and fittings can be found in Table Q1. The Darcy friction factor can be found in the Moody...
