Blood from two different patients is to be tested by having it flow through a long straight tube of length 10cm and internal diameter 6mm. A pressure drop of 50 dyne/cm² is imposed from one end of the tube to the other, and the resulting blood flow rate Q is measured. If the blood from patient A has a yield shear stress of 0.08 dynes/cm² and the blood from patient B has a yield shear stress of 0.12 dynes/cm², predict the ratio Q/Q3. Assume that the blood from both patients follows identical Casson rheology, with the exception of the difference in yield stresses.
