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