In the case of your FBD procedure, air or gasoline is accustomed to fluidize the bed of particles. This fluidization creates a turbulent and agitated ecosystem, enabling for successful heat and mass transfer.
(A diagram showing the forces exerted both on and by a system is likely to become puzzling since every one of the forces will terminate out.
