Extracted text: Solid particles having a size of 0.13 mm, a shape factor 0.88 and a density of 1000 kg/m³ are to be fluidized using air at 2.0 atm absolute and 25°C. The voidage at minimum fluidizing conditions is 0.5. If the cross section of the empty bed is 0.40 m² and the bed contains 400 kg of solid, calculate the minimum height of the fluidized bed and pressure drop at minimum fluidizing conditions. Data: µ =1.845×10°Pa -s p = 2.374 kg/m³ at 25 °C, 2 atm a) 5 m, 7756.73 Pa b) 1.5 m, 9776.73 Pa c) 2 m, 9776.73 Pa d) 2 m, 8676.73 Pa
