Mass Transfer An air-water vapour mixture has a dry bulb temperature of 60°C and a dew point temperature of 40°C. The total pressure is 101.3 kPa and the vapour pressure of water at 40°C and 60°C are 7.30 kPa and 19.91 kPa respectively.The humidity of air sample expressed as kg of water vapour/kg of dry air is 0.079 0.122 0.048 0.152 0.079 0.122 0.048 0.152 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Relative volatility varies with the concentration of component for an ideal solution. The relative volatity of a binary mixture may be defined as the ratio of vapor pressure of component 'A' to that of component 'B', when Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only vapor phase follows Raoult's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Only liquid phase obeys Dalton's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only vapor phase follows Raoult's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Only liquid phase obeys Dalton's law ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Pick out the wrong statement pertaining to leaching. Fine solids can not be leached in a Pachuka tank Vegetable seeds can be leached in either of Bollman extractor, Rotocel or Kennedy extractor Door classifier can be used for leaching of coarse solids Very high temperature is not needed for the leaching of sugar beet Fine solids can not be leached in a Pachuka tank Vegetable seeds can be leached in either of Bollman extractor, Rotocel or Kennedy extractor Door classifier can be used for leaching of coarse solids Very high temperature is not needed for the leaching of sugar beet ANSWER DOWNLOAD EXAMIANS APP
