ABSTRACT: This report presents and disscusses an experimnt to determine the minimum fluidization velocity and from there to determine the average size of the sand particles inside the fluidized bed. During the experiment, air was passed through a fluidized bed and the pressure drop was recorded. The Minimum fluidization velocity was found to be (0.2033 m/s), and the average diameter of the sand partical was found to be (1.102 mm) with a percentage error of (15.34 %). INTRODUCTION: Fluidized bed reactors are used commonly in a number of processing applications. The manner in which a bed becomes fluidized can be understood by passing gas upward through a bed of solids at an increasing velocity. This increasing flow rate of gas will cause a pressure drop across the bed. Once the minimum fluidization velocity is reached the pressure drop across the bed remains
