Question
Air at a dry bulb temperature of 40C and a
wet bulb temperature of 20C is first heated in
a heater to a dry bulb temperature of 90C.
Then it is passed through a bed of apricot
slices to dry them. The air existing from the
bed is at a dry bulb temperature of 60 C. It is
then passed through a dehumidifier to
reduce its relative humidity to 10%. Clearly
show the various paths of the process on a
psychrometric chart. Determine (a) the
amount of moisture removed from the bed
per kg of dry air (b) the amount of moisture
removed in the dehumidifier per kg of dry
air.
