Air in a factory for drying apricots had dry bulb temperature of (Tdry) 25oC and wet bulb temperature of (T wet) 15oC. What are the RH, dew point, Humidity ratio, specific volume and vapour pressure values.
Second we are drying 10 Kg apricots of 85% moisture in batch production ending up with 60 % moisture content using a fan that blows hot air. We measured the air characteristics and found that Tdry = 35 oC and Twet=28 oC. The fan is blowing 200Kg Dry air per hour.
Calculate the time needed to dry the apricotsType or paste question here

3. 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 exiting from the top of the apricot bed is at a dry bulb temperature of 60C. It is then passed through a dehumidifier to reduce its relative humidity to 10%. Clearly show the various paths of...
