9.16 Air at a dbt of 30 degrees C and a relative humidity of 30% is conveyed through a heated dryer where it is heated to a dbt of 80 degrees C. Then it is conveyed through a bed of granular pet food to dry it. The air exits the dryer at a dbt of 60 degrees C. The exit air is again heated to 80 degrees C and conveyed through another dryer containing another batch of pet food. The exit air from the second dryer leaves at saturation. Cleary show the path of air, starting from the ambient air to the saturated air exiting the second dryer on a copy of psychrometric chart. Determine the amount of water removed in the first and second dryer per kg of dry air.
