Abstract: In this report, an experiment about measuring the sand particles diameter in a bed was discussed. In order to calculate the diameter, the minimum fluidization velocity must be found. Air flowing from a compressor is passed through the fluidized sand bed. Pressure drop was measured at different flow rates. Graphically, the minimum fluidization velocity was 0.0622 m/s while 0.262 mm was found to be the average diameter of sand particles with an error percentage of 11%, reasons for high error percentage will be discussed in the report.

Introduction: Fluidized bed is commonly used in chemical industries. The main purpose to use them is to increase both the surface area and the contact time between the solid and the fluid. In our experiment the fluidized bed is built from two opposite glass walls sealed and filled with sand .At the bottom, a compressor is connected and the air flow upwards, the pressure drop is measured by a connected rotameter also, the bed height must be noted down for each run. Theoretical Background:
