Mechanical Operations If dp is the equivalent diameter of a non-spherical particle, Vp its volume and sp its surface area, then its sphericity is Φs is defined by Φs = dp Sp/Vp Φs = Vp/dp sp Φs = 6 Vp/dp sp Φs = 6 dp Sp/Vp Φs = dp Sp/Vp Φs = Vp/dp sp Φs = 6 Vp/dp sp Φs = 6 dp Sp/Vp ANSWER DOWNLOAD EXAMIANS APP
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 ∝ Re1.0 Po ∝ Re0.5 Po ∝ Re0.0 Po ∝ Re-1.0 Po ∝ Re1.0 Po ∝ Re0.5 Po ∝ Re0.0 Po ∝ Re-1.0 ANSWER DOWNLOAD EXAMIANS APP
