Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less Total pressure is less Saturated steam is used for steam distillation Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less Total pressure is less Saturated steam is used for steam distillation ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer It takes 6 hours to dry a wet solid from 50% moisture content to the critical moisture content of 15%. How much longer it will take to dry the solid to 10% moisture content, under the same drying conditions?

Mass Transfer Though, theoretically the adsorption & desorption isotherms is expected to coincide but sometimes at least a part of the isotherms does not coincide and this phenomenon is known as adsorption hysterisis. In such cases, the desorption equilibrium pressure is __________ that obtained for adsorption. Higher than Same as Lower than Either same or higher than Higher than Same as Lower than Either same or higher than ANSWER DOWNLOAD EXAMIANS APP
