Mass Transfer Air initially at 101. 3 kPa and 40°C and with a relative humidity of 50%, is cooled at constant pressure to 30°C. The cooled air has a Higher relative humidity Higher wet bulb temperature Higher dew point Higher absolute (specific) humidity Higher relative humidity Higher wet bulb temperature Higher dew point Higher absolute (specific) humidity ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In a distillation operation, what is the effect of the temperature of the reflux stream (given below) on the condenser and reboiler loads? Reflux conditions:(i) Reflux stream is completely liquid and is at its bubble point.(ii) Reflux stream is below its bubble point. Condenser load is the same in both the cases but reboiler load is higher in case (ii) Reboiler load is the same in both the cases but condenser load is higher in case (ii) Both condensor and reboiler loads are higher in case (ii) as compared to case (i) Condenser and reboiler loads are the same in both the cases Condenser load is the same in both the cases but reboiler load is higher in case (ii) Reboiler load is the same in both the cases but condenser load is higher in case (ii) Both condensor and reboiler loads are higher in case (ii) as compared to case (i) Condenser and reboiler loads are the same in both the cases ANSWER DOWNLOAD EXAMIANS APP
