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 Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less Saturated steam is used for steam distillation Total pressure is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Heat in BTU necessary to increase the temperature of 1 lb of gas and its accompanying vapour by 1°F is called the Humid heat Sensible heat Latent heat Specific heat Humid heat Sensible heat Latent heat Specific heat ANSWER DOWNLOAD EXAMIANS APP
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. Either same or higher than Higher than Same as Lower than Either same or higher than Higher than Same as Lower than ANSWER DOWNLOAD EXAMIANS APP
