Mass Transfer Penetration theory relates the average mass transfer co-efficient (K) with diffusivity (D) as K ∝ D2 K ∝ D1.5 K ∝ D K ∝ √D K ∝ D2 K ∝ D1.5 K ∝ D K ∝ √D ANSWER DOWNLOAD EXAMIANS APP
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 wet bulb temperature Higher dew point Higher absolute (specific) humidity Higher relative humidity Higher wet bulb temperature Higher dew point Higher absolute (specific) humidity Higher relative humidity ANSWER DOWNLOAD EXAMIANS APP
