Mass Transfer During dehumidification of unsaturated air wet bulb temperature & partial pressure of vapor are not constant. However, during evaporative cooling process with recirculated water supply, the __________ remains constant. Relative humidity Wet bulb temperature Partial pressure of water vapor None of these Relative humidity Wet bulb temperature Partial pressure of water vapor None of these ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In a binary distillation column, if the feed contains 40 mole % vapour, the q line will have a slope of -1.5 -0.6 1.5 0.6 -1.5 -0.6 1.5 0.6 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Total pressure is less Temperature 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 Total pressure is less Temperature 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 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Steam distillation is not recommended to be used, if the Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Liquids decompose, if distilled directly at atmospheric pressure Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Liquids decompose, if distilled directly at atmospheric pressure ANSWER DOWNLOAD EXAMIANS APP
