Two different fluids $($Fluid A and Fluid B$)$ that can be described by the Herschel$-$Bulkley model have yield stress of $0Pa.$ Following is the data for shear stress experienced by the fluids at different applied shear rate values. Based on the data, what type of flow behavior does the fluid A and fluid B exert? Calculate rheological parameters. Show detailed calculations and provide reasoning.
