When this quantity is zero, Burgers’ equation reduces to a quasi-linear hyperbolic differential equation. With pipe length and flow rate, this quantity (10[1])appears in the numerator of Poiseuille’s (-5[1])(“pwah-ZEY’s”) law for calculating (10[1]-5[1])pressure changes. (10[1])The Navier-Stokes equations (-5[1])reduce to the Euler (“OIL-er”) equations when this quantity (10[3])is zero. (10[4]-5[4])Stokes’ (-5[1])law states (10[1]-5[1])drag is proportional (10[3])to radius, (10[1])velocity, (10[1])and this (-5[1])quantity. (10[3])The Reynolds number (10[1]-5[1])is the ratio of inertial forces (10[1])to forces (10[1])due to this (-5[1])quantity. (10[3]-5[4])For (10[1])a non-Newtonian (10[1])fluid (10[1]-5[1])like cornstarch (-5[1])slurry, (10[3]-5[1])this quantity (10[1])depends on applied (10[1])stress. (10[2]-5[3])This quantity equals (10[2])zero in superfluids. (10[3]-5[2])For (10[1])10 points, (10[1])name this quantity (0[1])that measures a fluid's resistance (10[2])to (10[1])flow.
