Experiments will be conducted to verify the pressure decreases the minimum fluidized velocity and reduced pressure monitoring by using the theory of equations. Ergun in this trial, the air is allowed to pass through a column filled with a bed of avocado alumina particles. When I drag up to the action by air particles is equal to the weight of the particles in the bed, apparently the flow started to occur. The effects of flow rate, the air pressure decrease is observed. Feed rate of different weather and different column heights will receive. This information will be used to calculate the pressure theoretical combination of decreased over the column with the help of Ergun equation as. In addition, air flow rate, the pressure decreases, which is represented by the column packing fluidized, he also noted. A graph of pressure decrease when compared to the theoretical flow rate, the air gets to the plot. Reduced-pressure theory is compared with the pressure was reduced from the experiments that the minimum fluidized velocity by calculating the difference between the value of a hundred lalot down in theory and experiment with pressure.
