Mass Transfer - Engineering
Q1: 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 aA higher dew point.
B higher absolute (specific) humidity.
C higher relative humidity
D higher wet bulb temperature.
ANS:C - higher relative humidity To determine the changes in the air properties when cooled at constant pressure, we can use psychrometric principles. Given:
