Mass Transfer In liquid extraction, if the selectivity is unity, then Separation of the constituents is the most effective Amount of solvent required will be minimum No separation will occur Solvent flow rate should be very low Separation of the constituents is the most effective Amount of solvent required will be minimum No separation will occur Solvent flow rate should be very low ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The diffusivity (D) in a binary gas mixture is related to the pressure (P) as D ∝ P0.5 D ∝ 1/P1.5 D ∝ 1/P0.5 D ∝ 1/P D ∝ P0.5 D ∝ 1/P1.5 D ∝ 1/P0.5 D ∝ 1/P ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer A 25 cm x 25 cm x 1 cm flat sheet weighing 1.2 kg initially was dried from both sides under constant drying rate conditions. It took 1500 seconds for the weight of the sheet to reduce to 1.05 kg. Another 1m x 1m x 1cm flat sheet of the same material is to be dried from one side only.Under the same constant drying rate conditions, the time required for drying (in seconds) from its initial weight of 19.2 kg to 17.6 kg is 1000 1500 2500 2000 1000 1500 2500 2000 ANSWER DOWNLOAD EXAMIANS APP
