At low Reynold's number, the power (P) required for agitating a fluid in a stirred tank becomes independent of inertial forces. In this limit, indicate which of the following relations is satisfied:
P_o = ρ/ρN³ D⁵ : Power number
Re = ρ N D²/μ: Reynold's number
N is the impeller rotational speed, and D is the impeller diameter.
