Q6/ Breakfast cereal is being dried in a fluidized bed dryer in which the cereal moves roughly countercurrent to the air flow. The figure below show the process with the data placed on the respective stream flow. Determine the required inlet dry air flowrate in m/hr if the cereal must have a water content of no more than 14.0 percent. (DC = dry cereal). %3D 500kg/h airoulkpul( A.
