1. Purpose
• Through a fixed and fluidized bed equipment, we can observed the fluidization for packing bed with changing pressure.
• Observe the differences of a pressure drop and minimum fluidization velocity at both water and air as fluids.

2. Theory
2-1. Properties for immersed bodies
In fluid dynamics, drag (sometimes called air resistance or fluid resistance) refers to forces which act on a solid object in the direction of the relative fluid flow velocity. Unlike other resistive forces such as dry friction, which is nearly independent of velocity, drag forces depend on velocity.
