6: (a) Use the scaling laws to estimate the change of volumetric flow and pressure drop per unit length in a circular tube if the radius of the tube is reduced by a factor of 10. The pressure drop in a capillary tube is given by AP- 8uVavg.Lia. Here, L length of tube, a is the radius, g is the average speed of fluid and u is the viscosity). (b) Evaluate the resistance per unit length (R/L) for water flow (viscosity μ-100 1.65x10-5) in micro channels that have three different shapes: (a) circular tube, (b) rectangular tube and (c) V grooves. (diameter, 2a-30-um) _1One side, d-40 μm) (One side, w-so μm and angles are equal) Resistance (R/L) Shape What is your choice of designing micro channels for micro-fluidic devices?
