Mechanical Operations 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: Po = 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. Po ∝ Re-1.0 Po ∝ Re1.0 Po ∝ Re0.0 Po ∝ Re0.5 Po ∝ Re-1.0 Po ∝ Re1.0 Po ∝ Re0.0 Po ∝ Re0.5 ANSWER DOWNLOAD EXAMIANS APP
