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.
