T=20

X=1.5

please solve with steps

2) Solid pellets of 5 mm diameter are to be fluidized with 20 m/h of water at 1 atm and TC in a vertical cylindrical vessel. The density of the rounded solid particles is similar to the ones used in experiment. The given quantity of water is just sufficient to fluidize the solids. Determine the vessel diameter and terminal velocity. Show pressure drop versus superficial velcity characteristic curve showing both fixed and fluidized bed region. (Column height can be assumed 'X' times the column diameter). Suggest method how porosity of the particles can be obtained experimentally. (values of 'T' and 'X' will be given to you by instructor)
