3.1.4. Determination of the outlet and inlet conditions of
the first and second trays
Firstly, it is assumed that the inlet conditions of the
first tray are equal to the inlet conditions of drying
chamber. Throughout the mathematical expressions, it
should be known and taken into consideration that the
mass flow rates of drying air passed through the first
and second trays are equal to each other (Fig. 2).
For the 1st tray:
