Vid 15. One expression for the Reynolds number is Rem a. Since the Reynolds number must be dimensionless, what are the units of the v term in the denominator? b. Does the v term represent the kinematic or dynamic viscosity? c. Find the coefficient of drag of a sphere (d=0.5m) if cold air, with a density of 1.29 kg/m' is blowing on it with a velocity of 35 m/s and a dynamic viscosity of 1.72d0N s/m?.
