Mass Transfer Penetration theory relates the average mass transfer co-efficient (K) with diffusivity (D) as K ∝ D2 K ∝ D1.5 K ∝ √D K ∝ D K ∝ D2 K ∝ D1.5 K ∝ √D K ∝ D ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Pick out the correct relationship. (where, Ri = internal reflux ratio Ro = external reflux ratio. ) (1 + Ri) = Ro/Ri (1 + Ro) = Ro/Ri (1 - Ri) = Ro/Ri (1 - Ro) = Ro/Ri (1 + Ri) = Ro/Ri (1 + Ro) = Ro/Ri (1 - Ri) = Ro/Ri (1 - Ro) = Ro/Ri ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In distillation where q is defined as the moles of liquid flow in the stripping section per mole of feed introduced, for saturated liquid feed q = 1 q < 1 q > 1 q = 0 q = 1 q < 1 q > 1 q = 0 ANSWER DOWNLOAD EXAMIANS APP
