Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Saturated steam is used for steam distillation Total pressure is less Temperature is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Saturated steam is used for steam distillation Total pressure is less Temperature is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The wet and 'dry bulb temperature for a vapour-gas mixture are 25°C and 30°C respectively. If the mixture is heated to 45°C at constant pressure, the wet bulb temperature will be __________ °C. -25 25 > 25 < 25 -25 25 > 25 < 25 ANSWER DOWNLOAD EXAMIANS APP
