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 2000 2500 1000 1500 2000 2500 1000 1500 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Pick out the correct relationship. (where, Ri = internal reflux ratio Ro = external reflux ratio. ) (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 (1 - Ri) = Ro/Ri ANSWER DOWNLOAD EXAMIANS APP
