Air at a dbt (dry bulb temprature) of 30 °C and a relative humidity of 30% is conveyed through a heated dryer where it is heated to a dbt of 80 °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 °C. The exit air is again heated to 80 °C and conveyed through another dryer containing another batch of pet food. The exit air from the second dryer leave at saturation. Clearly show the paths of air, starting from the ambient air to the saturated air exiting the second dryer on a copy of a psychrometric chart. Determine the amount of water removed in the first and second dryer per kg of dry air.
