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 2500 1500 2000 1000 2500 1500 2000 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer At __________ reflux, theoretical number of plates in a distillation coloumn is calculated using Fenske-Underwood equation. Minimum Operating Total Maximum permissible Minimum Operating Total Maximum permissible ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In continuous distillation, the internal reflux ratio (Ri) and the external reflux ratio (Re) are related as Ri = (1 - Re)/Re Ri = Re Ri = Re/(1 + Re) Ri = Re/(1 - Re) Ri = (1 - Re)/Re Ri = Re Ri = Re/(1 + Re) Ri = Re/(1 - Re) ANSWER DOWNLOAD EXAMIANS APP
