You are developing a porous membrane for use in a dialysis system. The membrane must be able to retain both protein and glucose on the inlet side and allow other, smaller molecules to flow through. You have found that the membrane is 0.25 mm thick and contains long, rectangular pores with a width of 0.1 microns. 57% of the 50 cm^2 membrane surface area is covered with pores. A test fluid (viscosity = 1.5 cP, density = 1015 kg/m^3) is passed through the membrane. You can assume that the test fluid has a composition similar to that of blood plasma. An initial test is run at physiological conditions, and you observe that the flow rate of fluid through the membrane is 500 cm^3/min. Given this data, what must the hydrodynamic pressure drop across the membrane in your test system be in pascals?
What should be the surface tension of a liquid if its density, which is 1.44 g/cc, is the same as that of the calibrating liquid? The displacements of the liquid and the calibrating liquid inside the capillary tube are both 0.5 cm. The surface tension of the calibrating liquid is 29.4509 dynes/cm.
Case 1: Material system without density and viscosity differences Though unlikely in real life, in this case, we assume that all of the material in the homogenizer is of the same density and viscosity. Thus, only one set of material parameters are mentioned (density, ρ; dynamic viscosity, μ). The important parameters are listed as follows: Target quantity : Mixing time, θ Geometric parameters : Stirrer diameter, d Material parameters : Density, ρ Dynamic viscosity, μ Process-related parameters : Stirrer speed, n 1.1) Write out the relevance list for Case 1. 1.2) Generate the pi-set for this case. 1.3) Write out the appropriate pi (π) numbers from the generated pi-set. 1.4) Identify the established dimensionless numbers from the derived pi (π) numbers. 1.5) Write the possible relationship of the dimensionless numbers for Case 1.
