Mass Transfer The diffusivity (D) in a binary gas mixture is related to the pressure (P) as D ∝ 1/P0.5 D ∝ 1/P1.5 D ∝ 1/P D ∝ P0.5 D ∝ 1/P0.5 D ∝ 1/P1.5 D ∝ 1/P D ∝ P0.5 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 1500 1000 2500 2000 1500 1000 2500 2000 ANSWER DOWNLOAD EXAMIANS APP
