Question: Wet solids pass through a continuous dryer. Hot dry air enters the dryer at a rate of 5 0 0 0 k g m i

Wet solids pass through a continuous dryer. Hot dry air enters the dryer at a rate of 5000
kgmin and mixes with the water that evaporates from the solids. Humid air leaves the dryer
at 38C and 40% relative humidity and then passes through a condenser in which it is cooled
to 17C. The pressure is constant at 1atm throughout the system. Use the psychrometric
chart to answer the following questions.
a)(5 pts) What is the moisture content (=absolute humidity) in the humid air stream leaving
the dryer (in kgkg Dry Air)? Report with 3 digits of precision in decimal format.
b)(5 pts) What is the wet bulb temperature of the humid air stream leaving the dryer (in {:C)?
Report answer with 3 digits of precision in decimal format.
c)(5 pts) As the humid air cools upon entering in the condenser, at what temperature will the
water just begin to condense? Report answer in deg. C in decimal format with 3 digits of
precision.
d)(5 pts) Assuming the air entering the condenser is in there long enough to come to 17C
and leave in equilibrium with the condensed liquid water at that temperature, what is the
absolute humidity (in kgkg DryAir) of the air leaving the condenser? Report answer with 3?
digits of precision in decimal format on Canvas.
e)(5 pts) If that air leaving the condenser were then heated back up to 38C, what would the
decimal format on Canvas.
