Air at 50 ° C with 1.7 bar gauge pressure enters the cylindrical bearing system, the diameter of which is below, and standing in an upright position, with an average flow rate of 2.6 m / s for drying purposes. In the fluid state, the porosity value of the bed is desired to be 0.61 m and its height 0.53 m. Inside the bed are fresh kidney beans with a diameter of 8 mm.
a). When the air enters the bed, is the inlet speed of the air sufficient for the bed to be in a fluid form as desired above, or is it necessary to adjust the air speed in accordance with the desired conditions?
b). Find the drag force that acts on a single kidney bean while the bearing is fluid.
c) What is the absolute pressure value of the air when leaving the fluidized bed?

You can get the density of kidney bean grains 1120 kg / m.
The diameter of the bed is 18 cm
