Mass Transfer In distillation column design, the McCabe-Thiele procedure is inadequate and a Ponchan-Savarit procedure is needed, when An azeotrope forms Saturated feed is not used A total condenser is used The latent heat of vaporisation of the more and less volatile components are greatly different An azeotrope forms Saturated feed is not used A total condenser is used The latent heat of vaporisation of the more and less volatile components are greatly different 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 + Ri) = Ro/Ri (1 - Ro) = Ro/Ri (1 + Ro) = Ro/Ri (1 - Ri) = Ro/Ri (1 + Ri) = Ro/Ri (1 - Ro) = Ro/Ri (1 + Ro) = Ro/Ri ANSWER DOWNLOAD EXAMIANS APP
