Mass Transfer Unsaturated air (with dry bulb temperature and dew point being 35°C and 18°C respectively) is passed through a water spray chamber maintained at 15°C. The air will be cooled And dehumidified with decrease in wet bulb temperature And dehumidified with increase in wet bulb temperature And humidified At the same relative humidity And dehumidified with decrease in wet bulb temperature And dehumidified with increase in wet bulb temperature And humidified At the same relative humidity ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer For the gas absorption, the height of a transfer unit, based on the gas phase is given by (G: superficial molar gas velocity, L: superficial molar liquid velocity, FG:mass transfer co-efficient, mols/m² , a: in-terfacial area per unit volume of tower) L/(FG.G) F/(FG.a) (G.a)/FG FG/(G.a) L/(FG.G) F/(FG.a) (G.a)/FG FG/(G.a) ANSWER DOWNLOAD EXAMIANS APP
