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.

Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.
